Exploits and vulnerabilities in Q2 2026

The vulnerability landscape shifted significantly in Q2 2026. First, the number of registered CVEs reached an unprecedented level. This is driven primarily by the widespread adoption of AI, both for application development and search for security flaws. This resulted in entire new classes of vulnerabilities emerging, particularly in the Linux networking subsystem. Second, security researchers have been publishing exploits for unpatched vulnerabilities more frequently. Publications like these can generate significant fallout, since they potentially open the door for attackers to target unprotected systems. Statistics on registered vulnerabilities This section provides statistical data on registered vulnerabilities. The data comes from Kaspersky’s vulnerability knowledge base, which draws on the CVE database as well as the Russian BDU database and GitHub Advisory (GHSA). As a result, the figures for previous reporting periods may differ from those published in earlier reports. We examine the number of registered vulnerabilities for each month over the last five years. As the chart below shows, this number continues to surge, a trend reflected across all the databases we track. It’s driven primarily by the widespread adoption of AI tools: as we predicted in our previous report, these tools have played a major role in the discovery of vulnerabilities in third-party software. Meanwhile, these tools often contain security issues of their own. For example, OpenClaw, a popular AI project, ranked 12th among those with the highest number of vulnerabilities discovered and published in Q2, with over 200 CVEs registered during the reporting period. Finally, AI development tools are also contributing to the vulnerability landscape, since the quality of the code they produce can vary widely. Therefore, the rate at which new vulnerabilities are discovered will inevitably keep growing. Total published vulnerabilities per month from 2022 through 2026 (download) Next, we analyze the number of new critical vulnerabilities (CVSS > 9.0) over the same period. Total critical vulnerabilities published per month from 2022 through 2026 (download) As the chart shows, the number of published critical vulnerabilities jumped sharply in Q2. This is because using AI for vulnerability research makes it possible to analyze massive amounts of previously unexamined code, uncover new attack surfaces, and identify entire classes of vulnerabilities that have gone unnoticed for decades. In particular, AI was used to find a series of Dirty Frag vulnerabilities in the Linux kernel. Exploitation statistics This section presents statistics on vulnerability exploitation for Q2 2026. The data draws on open sources and our telemetry. Windows and Linux vulnerability exploitation Q2 2026 saw a new precedent in the publication of vulnerabilities in Windows components and exploits for these: researchers no longer waiting for CVE registration, let alone patches. A case in point: a researcher who goes by Nightmare Eclipse (also known as Chaotic Eclipse) published a list of new “named” vulnerabilities across various Windows subsystems. At the time the technical details were published, none of the vulnerabilities had been assigned a CVE identifier: BlueHammer: a local privilege escalation vulnerability in Windows Defender. During signature database updates, a time-of-check to time-of-use (TOCTOU) race condition occurs, allowing an attacker to substitute the directory where temporary update files are written. The researcher published a fully functional exploit for the vulnerability. RedSun: another logical vulnerability in Windows Defender with a working exploit. Suspicious and malicious files marked as “cloud” can be overwritten or restored to their original directory with elevated privileges. The exploit incorporates fragments of algorithms that make it possible to leverage various logical vulnerabilities in Windows, effectively combining a large number of popular exploitation techniques. YellowKey: a vulnerability that lets the user bypass BitLocker full-disk encryption and access system data through the Windows Recovery Environment (WinRE). A fully functional exploit was also published. GreenPlasma: a vulnerability that enables system object injection via the CTF loader for the Collaborative Translation Framework (CTFMON) service in Windows. The original publication included an exploit with limited functionality. RougePlanet: yet another Windows Defender vulnerability that, like BlueHammer, stems from a TOCTOU issue, this time in the engine responsible for real-time system scanning. The published exploit uses the vulnerability to overwrite the system file wermgr.exe with a malicious one. UnDefend: another vulnerability in the Windows Defender service. This time, the exploit causes a denial of service and blocks updates. Even though such cases remain isolated for now, we believe they’ll grow into a full-fledged trend. Early publication of exploits gives attackers an advantage over software developers, who are left with no time to fix the issues. Veteran vulnerabilities in Windows software also remain relevant. These are the ones our solutions most frequently detect exploits for: CVE-2018-0802: a remote code execution (RCE) vulnerability in the Equation Editor component CVE-2017-11882: another RCE vulnerability also affecting Equation Editor CVE-2017-0199: a vulnerability in Microsoft Office and WordPad that allows an attacker to gain control over the system CVE-2023-38831: a vulnerability in WinRAR that involves improper handling of objects within an archive CVE-2025-6218 (formerly ZDI-CAN-27198): another WinRAR vulnerability allowing the specification of relative paths to extract files into arbitrary directories, potentially leading to malicious command execution CVE-2025-8088: a vulnerability similar in exploitation method to CVE-2025-6218. The attackers used NTFS Streams to circumvent controls on the directory into which files are being unpacked The vulnerabilities listed here can be leveraged to gain initial access to a vulnerable system and for privilege escalation. This underscores the critical importance of timely software updates. That said, the number of Windows users who encountered exploits declined slightly in Q2, hitting an 18-month low. Dynamics of the number of Windows users encountering exploits, Q1 2025 – Q2 2026. The number of users who encountered exploits in Q1 2025 is taken as 100% (download) Linux also hit a rough patch in Q2 2026. Specifically, the period saw the disclosure of the Dirty Frag family of vulnerabilities, which lets an attacker reliably escalate privileges within the operating system. All the vulnerabilities published in Q2 2026 were, in one way or another, related to the Linux caching subsystem. Here are the ones being most actively exploited: CVE-2026-31431 (Copy Fail): a local privilege escalation vulnerability in the Linux kernel that lets an unprivileged user modify the page cache and gain root privileges. Especially dangerous for cloud and containerized environments CVE-2026-43284, CVE-2026-43500 (Dirty Frag): a family of vulnerabilities in the Linux networking subsystem (IPsec ESP and RxRPC) that lets a local user overwrite the page cache and escalate privileges to root CVE-2026-46300 (Fragnesia): a local privilege escalation vulnerability in the Linux kernel related to packet fragment handling and the page cache mechanism. It lets an unprivileged user gain root privileges and is also classified as part of the Dirty Frag family CVE-2026-31635 (DirtyDecrypt): a Linux kernel vulnerability that lets a local attacker escalate privileges due to improper handling of decryption operations and page cache data modification CVE-2026-43494 (PinTheft): a Linux kernel vulnerability that lets a local user gain elevated privileges due to errors in the memory page pinning mechanism CVE-2026-46331 (pedit COW): a vulnerability in the Linux kernel’s traffic control subsystem (tc-pedit) that exploits a flaw in copy-on-write to modify the page cache and subsequently escalate privileges to root The vulnerabilities described above were quickly embraced by attackers. At the same time, our solutions continue to detect exploitation attempts targeting older vulnerabilities as well: CVE-2022-0847: a vulnerability known as Dirty Pipe, which enables privilege escalation and the hijacking of running applications CVE-2019-13272: a vulnerability caused by improper handling of privilege inheritance, which can be exploited to achieve privilege escalation CVE-2021-22555: a heap out-of-bounds write vulnerability in the Netfilter kernel subsystem CVE-2023-32233: another Netfilter subsystem vulnerability that allows for Use-After-Free conditions and privilege escalation through improper processing of network requests Dynamics of the number of Linux users encountering exploits, Q1 2025 – Q2 2026. The number of users who encountered exploits in Q1 2025 is taken as 100% (download) In Q2 2026, the number of Linux users who encountered exploits declined slightly compared to Q1. Given that a significant share of new vulnerabilities are tied to the operating system’s caching subsystem, we recommend installing patches as quickly as possible, or disabling vulnerable kernel modules if patching isn’t an option. Most common published exploits The distribution of published exploits by software type in Q2 2026 includes categories that haven’t appeared in the sample for a long time. For instance, we’re once again seeing exploits targeting SharePoint. It’s worth noting that while several vulnerability write-ups for Exchange and SharePoint were published during the quarter, most turned out to be fake, AI-generated research. While the articles and exploit source code themselves look fairly polished, they describe nonexistent problems in the software or its components — often close to genuinely vulnerable mechanisms — in order to mislead researchers. This type of attack is aimed at increasing the time it takes to detect real vulnerabilities. In some cases, the description of a nonexistent vulnerability came bundled with completely unrelated malware. Distribution of published exploits by platform, Q1 2026 (download) Distribution of published exploits by platform, Q2 2026 (download) Vulnerability exploitation in APT attacks We analyzed which vulnerabilities were exploited in APT attacks during Q2 2026. The rankings provided below include data based on our telemetry, research, and open sources. TOP 10 vulnerabilities exploited in APT attacks, Q2 2026 (download) In Q2 2026, a trend emerged in APT attacks toward exploiting new vulnerabilities right from the moment they’re published. As before, we’re also seeing a large number of zero-day vulnerabilities. The Langflow vulnerability deserves particular attention: it’s one of the first cases of an APT group exploiting AI technology, which many organizations are only just beginning to integrate. Because most of this tech is proprietary, it has a considerable number of security blind spots. Therefore, given the growing number of AI-based automation tools, we strongly recommend going beyond the usual patching and developing secure procedures for credential use and sensitive data handling in systems that rely on agents and LLMs. C2 frameworks In this section, we examine the most popular C2 frameworks used by APT groups and analyze the vulnerabilities targeted by the exploits that interacted with C2 agents in APT attacks. The chart below shows the frequency of known C2 framework usage in attacks during Q2 2026, according to open sources. TOP 10 C2 frameworks used by APTs to compromise user systems, Q2 2026 (download) Sliver, Havoc, AdaptixC2, and Metasploit remain the most widely used C2 frameworks. After studying open sources and analyzing samples of malicious C2 agents that contained exploits, we determined that the following vulnerabilities were utilized in APT attacks involving the C2 frameworks mentioned above: CVE-2026-35273: a vulnerability in Oracle PeopleSoft PeopleTools that security vendors classify as server-side request forgery (SSRF). The details of the vulnerability have never been disclosed, although some research covers the post-exploitation steps CVE-2023-46604: an insecure deserialization vulnerability in Apache ActiveMQ that allows arbitrary code execution in the context of the service process CVE-2024-12356 and CVE-2026-1731: command injection vulnerabilities in BeyondTrust software that allow an attacker to send malicious commands even without system authentication CVE-2023-36884: a vulnerability in the Windows Search component that allows commands to be run on the system, bypassing the mark-of-the-web (MoTW) mechanism CVE-2025-53770: an insecure deserialization vulnerability in Microsoft SharePoint that allows for unauthenticated command execution on the server CVE-2025-8088 and CVE-2025-6218: similar directory traversal vulnerabilities in WinRAR that allow files to be extracted from an archive to a predetermined path, potentially without the archiving utility displaying any alerts to the user These vulnerabilities show that attackers used them for initial access and privilege escalation on vulnerable systems, setting the stage for launching a C2 agent. They include both zero-day vulnerabilities and fairly well-known security issues. LLM/AI tool vulnerabilities This section analyzes data published in Kaspersky’s vulnerability knowledge base. We reviewed the Q2 2026 version of the knowledge base. As mentioned above, AI tools, plugins, and technologies have proven fairly effective at automating the search for problematic code and anomalous behavior. The high speed at which new vulnerabilities are being discovered has naturally created a need to fix them just as quickly. AI is often used for this too, which increases the volume of code being generated. However, neither code written without human involvement nor AI-generated advice is always correct. The chart below covers registered vulnerabilities in AI tools for 2025–2026. Number of published vulnerabilities in LLMs, AI tools, and plugins with similar functionality, 2025–2026 (download) As the charts show, AI tools are racking up a substantial number of registered vulnerabilities, and that number keeps growing quarter over quarter. It’s also worth looking at how AI tool vulnerabilities break down by type, according to the CWE system: TOP 6 vulnerability types in products that implement or use AI/LLM logic, 2025–2026 Interestingly, vulnerabilities of an undetermined type have ranked first in every quarter since the start of 2025. Traditionally-made software has the same issue, and it doesn’t look like the growing number of AI tools will fix it. It’s also notable that the list includes classes CWE developers themselves don’t recommend using for vulnerability classification, since they lump together a whole range of more specific types. CWE-284 is an example of this. Looking at the most common classes, the key issues found in AI-related software can be summed up as follows: Inadequate access control over critical system objects Improper implementation of authentication and authorization mechanisms Injections It’s worth noting that injection-related vulnerabilities were relatively rare before AI agents took off (previously, they mostly affected web apps). Recently, though, these security issues have become relevant again. Looking back at a year and a half of the AI boom, one conclusion stands out regarding registered vulnerabilities: AI tool developers are more focused on expanding functionality than on security. This is worth keeping in mind when using these tools. Let’s look at the projects and applications that either integrated AI tools or offered them as the core product. Below is a list of the those with the highest number of registered vulnerabilities for 2025–2026. TOP AI/LLM-related projects by number of published vulnerabilities, 2025–2026 (download) Notable vulnerabilities This section highlights the most significant vulnerabilities published in Q2 2026 that have publicly available descriptions. Since the above already covers several significant vulnerabilities published during the reporting period, this section consists mainly of LLM/AI tool vulnerabilities. CVE-2026-25253: a gatewayUrl vulnerability in OpenClaw The issue stems from the fact that the OpenClaw user interface trusts the value of the gatewayUrl parameter passed in the URL and automatically establishes a WebSocket connection to the specified address. During this connection process, it sends an authentication token without any additional user confirmation. The attack algorithm exploiting this vulnerability works as follows: The application obtains a critical connection address from an external source (the gatewayUrl URL parameter), which is controlled by the attacker. There is no validation before use. The client automatically initiates a connection to the address specified in the parameter, which belongs to the attacker. While connected, the application sends credentials (an access token) to the specified address. If the attacker obtains a valid token, the consequences depend on that token’s level of access within the system. In general, this could lead to: User session compromise Execution of operations on the user’s behalf Modification of the AI agent configuration Unauthorized access to tools and resources connected to the agent Under certain OpenClaw configurations, further compromise of the host running the agent It’s worth noting that the risk of exploitation arises from a combination of several factors: the automatic connection and token transmission, the lack of address trust verification, and the high privileges granted to the local AI agent. CVE-2026-41948: a path traversal vulnerability in the Dify AI platform The vulnerability lets an authenticated user craft a request that enables the application to escape its permitted tenant and gain access to internal REST APIs that weren’t meant for that user. The root cause is insufficient normalization and validation of the URL path before it’s passed to the internal service. Depending on the Dify configuration, the consequences can include: Unauthorized access to internal service interfaces Breach of isolation between workspaces Exposure of internal service information Conditions favorable to further attacks when combined with other vulnerabilities The use of Dify in enterprise AI platforms is particularly risky, since internal services there tend to hold elevated privileges. CVE-2026-45386: an improper access control vulnerability in Open WebUI In Open WebUI, pin/unpin operations on messages are write operations, since they modify that message’s metadata (is_pinned, pinned_by, pinned_at). In vulnerable versions, however, before performing these actions, the API only checked for read access to the channel (a chat between a user or group and the AI) containing the message, not permission to modify its content. As a result, a user with a role limited to viewing messages could still change a message’s pinned status. The vulnerability’s mechanism works as follows: The user initiates an action that changes the state of an object. The application treats this action as a regular read request. Only channel view permission is checked. The application performs a write without verifying the required user authorization. This violates one of the fundamental principles of access control models — namely, that any operation that changes the state of data must be checked for the appropriate write or moderation permissions, regardless of whether the object itself is readable. Although the vulnerability doesn’t lead to arbitrary code execution or compromise of sensitive data, it can affect data integrity and collaborative workflows. Potential consequences of exploitation include unauthorized pinning or unpinning of messages, disruption of channel moderators’ and administrators’ activities, changes to the display order of important information, and even the potential spread of false or misleading information by altering the channel containing a pinned message. Open WebUI is widely used as an interface for interacting with local and enterprise LLMs. In these systems, pinned messages often contain important instructions, announcements, or tips for users. The ability to modify them with minimal privileges can disrupt collaborative workflows, cause confusion, and undermine trust in information published by administrators and moderators. CVE-2026-45501: a vulnerability in Microsoft Exchange The vulnerability stems from improper neutralization of user input when generating Exchange web pages. As a result, the browser may interpret specially crafted data as active content instead of plain text. Although Microsoft categorizes the potential impact of exploiting this vulnerability as spoofing, flaws like this can lead to alteration of displayed content, imitation of trusted interfaces, actions on behalf of the user within an active session, and abuse of user trust. It’s worth noting that issues like this are still relevant in modern software, given that mechanisms like Content Security Policy and various parsers were specifically created to help developers neutralize dangerous parts of user page content. Conclusion and advice Q2 brought the first significant results of AI automation adoption in software development and vulnerability hunting tools. This research shows that beyond traditional patch management, organizations now need real-time monitoring of systems and access controls, since infrastructure and everyday applications now contain far more AI functionality that could lead to compromise. Accordingly, besides quickly detecting infrastructure vulnerabilities and managing security patches, modern enterprise-grade security solutions need to provide a broad range of preventive measures for tracking the overall health of systems and workstations. Kaspersky Next meets these requirements by combining proactive mechanisms with the ability to respond promptly to emerging threats.

API Security Affairs CVE-2026-60004 ↗

U.S. CISA adds Gitea flaw to its Known Exploited Vulnerabilities catalog

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Gitea flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added an Oracle HTTP Server and Oracle Weblogic Server Proxy Plug-in flaw, tracked as CVE-2026-60004 (CVSS score of 9,8), to its Known Exploited Vulnerabilities (KEV) catalog. Gitea is an open-source platform for hosting and managing Git repositories. Think of it as a self-hosted alternative to GitHub or GitLab. CVE-2026-60004 is a critical remote code execution flaw that allows an attacker with write access to a repository to execute arbitrary shell commands as the Gitea service user. The flaw affects Gitea versions from 1.17 and was fixed in 1.27.1. The vulnerable diffpatch API can be abused to plant and execute a malicious Git hook. Because Gitea enables open registration by default, an unauthenticated attacker can create an account, create a repository, and exploit the flaw without existing credentials. A reported attack used the vulnerability to deploy a cryptocurrency-miner-like payload after an exposed Gitea instance allowed open registration and anonymous access to its web interface. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaw by August 28, 2026.

Hackers abuse npm mirrors to host phishing redirect pages

Threat actors are abusing npm and its mirrors to host malicious HTML pages that impersonate Cloudflare CAPTCHAs to redirect visitors to attacker-controlled websites. The technique was previously spotted in July by security researcher inf0stache, who found a 'china_airlines' npm package that used a fake Cloudflare verification page to redirect visitors to a malicious domain, and was also reported by IntelFusions. In a later report, OX Security discovered 24 npm packages containing the same malicious HTML page hosted on npm and various mirrors. However, unlike the typical npm supply-chain attacks we've seen lately, installing the packages does not infect a developer's computer with malware or infostealers. Instead, attackers use the npm registry as free storage for malicious HTML pages, which are then copied by mirroring platforms like UNPKG and npmmirror.

Microsoft PowerToys adds Alt+Tab-style switching for an app's windows

Microsoft updated its Windows PowerToys toolset with a new utility dubbed "Window Hopper" that lets users switch between an app's windows more quickly. The Window Hopper added in this release works like the standard ALT + TAB Windows feature, but it only works for the currently focused app, helping users switch back and forth between its windows. "Once the utility is enabled, press the configurable Alt + backtick shortcut to cycle through that app's windows without stepping through everything else on your desktop," Microsoft explains. "It is especially useful when you're juggling multiple browser windows, terminals, File Explorer windows, or editor instances." Those who want to customize the default activation keyboard shortcut can also do so in PowerToys settings to switch to the next and previous app window.

Hackers breached over 270 Zimbra servers in ongoing attacks

Threat actors have already compromised over 270 Zimbra instances in remote code execution attacks targeting a high-severity Zimbra Collaboration Suite (ZCS) vulnerability. The ZCS email and collaboration suite is used by hundreds of millions of people and organizations, including thousands of businesses and hundreds of government agencies worldwide. Synacor patched the security flaw (tracked as CVE-2026-73570), which allows unauthenticated attackers to gain code execution remotely by exploiting a command injection weakness in the SNMP monitoring component when SNMP notifications are enabled, with the release of ZCS version 10.1.20 on July 20. CERT Polska, the Polish Computer Emergency Response Team (CERT), first flagged the vulnerability as targeted in the wild last Monday, when it also warned security teams to check their logs for suspicious activity, including the Zimbra service restarting unexpectedly, and for files created in the /opt/zimbra/jetty/webapps/, /opt/zimbra/jetty_base/webapps/, and /tmp/ folders by user zimbra over the last 30 days.

Fake Minecraft Sites Are Still Spreading WeedHack After C2 Takedown

WeedHack Minecraft Malware Survives C2 Takedown: Fake Client Sites Still Active, SEO Poisoning Puts Malicious Downloads at the Top of Google McAfee Labs published a follow-up report on the WeedHack Malware-as-a-Service campaign this week, documenting ten active malicious sites and multiple file-hosting accounts that are still spreading the infostealer despite a disruption to its command-and-control infrastructure. Over the past month alone, McAfee WebAdvisor blocked more than 6,300 user attempts to reach these sites. WeedHack was first spotted in early June 2026 when McAfee researcher Aayush Tyagi documented a Malware-as-a-Service operation that had been running since January and had logged 116,464 infected systems, adding between 2,000 and 3,000 new victims every day. The operation offered a free tier that anyone with a Discord account could access, a premium tier with webcam surveillance capability for $5 a month, and a dashboard letting operators view stolen credentials, configure custom payloads, and monitor victims in real time. It spread through fake Minecraft client websites, YouTube videos linking to malicious downloads, and SEO poisoning that pushed those fake sites to the top of search results for popular Minecraft tool names. The malware stole session cookies, passwords, browser data, and cryptocurrency wallet contents, and used EtherHiding, a technique that fetches the attacker’s active server address from the Ethereum blockchain, to maintain contact with its infrastructure even when individual servers were shut down. “During our investigation of this campaign, we observed that most of these websites appear legitimate, as they are well-crafted and often mimic legitimate websites. We observed a series of dedicated brand-impersonation attacks targeting several popular Minecraft clients.” reads the report published by McAfee. “We published the original article in the first week of July, and, as a result, we’ve seen a disruption in WeedHack’s campaign: its C2 server is no longer active. Consequently, we have observed a shift in tactics by these attackers.  “ The dashboard is gone. The distribution sites are not. Each fake website copies the real tool’s features, FAQs, installation steps, developer information and even links to legitimate GitHub repositories. The sites look detailed and convincing, so most users have little reason to suspect anything. The attackers also use search rankings to reach victims. Researchers found that the first two Google results for “Xenon Client,” a popular Minecraft client, led to fake sites distributing WeedHack. The sites offered installation guides, free and paid downloads, and links to the real Xenon Client GitHub repository. A player searching for the tool, clicking the first result and downloading the file could easily end up installing malware. The campaigns exploit a structural weakness in the Minecraft modding community: many popular tools don’t have official websites, only GitHub pages and Discord servers. Nova-client.com is a fake website for a client that has no real website; the attackers built one and ranked it above the genuine GitHub repository. 22qq-client.com does the same for a Crystal PVP mod. For nova-client.com, the researchers specifically noted that the credits section lists generic team names instead of anyone who actually worked on the project, which is one of the cleaner ways to spot an impersonation if you know who the real developers are. One site in the campaign was built using lovable.app, an AI-powered web application builder that accepts natural language instructions and produces working sites. The platform is legitimate; the use here is not. The ready availability of tools like this means the cost and technical skill required to launch a new convincing fake gaming site is now close to zero. McAfee found that most malicious links came through Discord (49.6%), followed by MediaFire (23.4%), GitHub (8.2%) and Dropbox (4.6%). One Discord channel promoting fake DonutSMP clients had more than 1,900 members, while another site offered eight different mods that all delivered the same malware. The campaign also spread through trusted Minecraft communities such as Planet Minecraft and EndMods, making the scams harder to spot because users already trusted these platforms. McAfee recommends downloading mods and clients only from official developer repositories or trusted platforms such as Modrinth and CurseForge. If a tool asks you to disable antivirus protection, treat it as malware. Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, malware)
