U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Red Hat, Linux Kernel, Ajax.NET Professional, Microsoft SQL Server, and Citrix NetScaler flaws to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the following vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog: CVE-2015-3246 Red Hat Libuser Race Condition Vulnerability CVE-2015-5287 Red Hat Automatic Bug Reporting Tool Privilege Escalation Vulnerability CVE-2019-1068 Microsoft SQL Server Remote Code Execution Vulnerability CVE-2021-23758 Ajax.NET Professional Deserialization of Untrusted Data Vulnerability CVE-2022-0995 Linux Kernel Out-of-Bounds Write Vulnerability CVE-2026-8452 Citrix NetScaler ADC and NetScaler Gateway Improper Restriction of Operations within the Bounds of a Memory Buffer Vulnerability CVE-2015-3246 is a race condition in Red Hat libuser that could let an authenticated local user corrupt /etc/passwd to cause denial of service or escalate privileges. CVE-2015-5287 is a privilege escalation bug in Red Hat Automatic Bug Reporting Tool that could allow local users with certain permissions to gain higher privileges via a symlink attack on a predictable file. CVE-2019-1068 is a remote code execution flaw in Microsoft SQL Server that could allow an attacker to execute code in the context of the SQL Server Database Engine service account. CVE-2021-23758 (CVSS score not specified in the KEV notice) is a deserialization of untrusted data vulnerability in Ajax.NET Professional that could allow for remote code execution via arbitrary .NET classes. CVE-2022-0995 (CVSS score not specified in the KEV notice) is an out-of-bounds memory write vulnerability in Linux Kernel that could allow a local user to gain privileged access or cause a denial of service on the system. CVE-2026-8452 (CVSS score not specified in the KEV notice) is an improper restriction of operations within the bounds of a memory buffer vulnerability in Citrix NetScaler ADC and NetScaler Gateway that could lead to denial-of-service and has been observed under active exploitation in the wild. 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 flaws CVE-2019-1068 and CVE-2026-8452 by August 29, 2026, while the remaining must be addressed by September 9, 2026.

Cybersecurity researchers have discovered a cluster of 18 Google Chrome and one Microsoft Edge extensions that were published over the last six months and harbored wallet secret stealing and cryptocurrency draining capabilities. The extensions, per Socket security researcher Karlo Zanki, share similarities in code and tradecraft, with evidence indicating that the campaign may have been active
An Identity Fabric knits fragmented identity systems into a coherent layer that observes how identities behave across applications, APIs, and infrastructure. As enterprise access spans more cloud services and automated workloads, identity security depends less on static configuration and more on runtime visibility. This article covers the architecture, the risks of unmanaged identities, and
ServiceNow has released patches for four security flaws impacting the ServiceNow AI Platform, three of them rated 10.0 on the CVSS scoring system and exploitable, in certain circumstances, by an unauthenticated attacker. The company said it deployed a security update to hosted instances and provided the update to its partners and self-hosted customers, which leaves organizations that run their
VulnCheck has disclosed two previously undocumented factory implants in firmware for routers built by Shenzhen Zhibotong Electronics (ZBT), each of which gives an unauthenticated remote attacker the ability to run commands as root on affected devices. The implants, named SPEAKINGSTONE and DARKLANTERN by the company's zero-day research team, are tracked as CVE-2026-74232 and CVE-2026-74233.
cPanel has released patches for a security flaw affecting domain parking and addon domain functionality in cPanel and WebHost Manager (WHM), which could allow code execution as the root user. The vulnerability, assigned the CVE identifier CVE-2026-65643, impacts all supported versions of cPanel & WHM. cPanel described the issue as a critical security vulnerability and said that an
