Attempts to exploit a critical vulnerability (CVE-2026-71362) in Adobe's Commerce and Magento e-commerce platforms have been detected, potentially allowing attackers to hijack customer accounts. The flaw is described as an incorrect authorization vulnerability that could be leveraged to "gain elevated access to sensitive resources" without authentication and is one of the seven issues that Adobe addressed in a security update yesterday. Although the software vendor states in the advisory that it is not aware of exploits in the wild for any of the fixed flaws, eCommerce security company Sansec says that its Shield web application firewall (WAF) is already blocking CVE-2026-71362 exploitation attempts. According to Sansec, exploiting the vulnerability requires "no existing account, administrator privileges or user interaction."

Based on current cybersecurity best practices and frameworks, the resource package outlines cost-effective, actionable and customizable steps that K-12 institutions can take to develop and maintain effective cybersecurity programs.
Mozilla has scrapped the cryptographic key behind Firefox and Thunderbird downloads for Linux after an unencrypted copy of it was committed by mistake to one of the company's own private code repositories.

Mozilla has scrapped the cryptographic key behind Firefox and Thunderbird downloads for Linux after an unencrypted copy of it was committed by mistake to one of the company's own private code repositories. That key is how a user, or a Linux distribution packaging the browser, confirms a downloaded Firefox tarball came from Mozilla and was not tampered with. That decision carries a cost for anyone who checks what they download: files signed with the old key stop verifying once a user imports the revocation. That covers older Firefox and Thunderbird downloads, not just future ones. Nothing so far points to anyone outside the company getting hold of the key. The repository was private, the browser maker says a review of available audit records turned up no sign of unauthorized access, and everyone who could see it already had legitimate access anyway. Mozilla revoked it regardless.
In July 2026, Kaspersky experts detected a new attack by the Head Mare group. Previously, we classified them as hacktivists, but now we define them as an APT group due to the sophistication of their TTPs and the absence of destructive activity (encryption, wiping) in the targeted infrastructures. In this latest campaign, the attackers exploited a chain of vulnerabilities in the TrueConf video conferencing server and replaced the original TrueConf client installers with infected versions that installed the PhantomCore malware on the system. An investigation of the compromised server revealed that the attackers used a combination of two new vulnerabilities (assigned internal identifiers KLCERT-26-057 and KLCERT-26-058), allowing them to execute arbitrary code with the highest privileges. This web shell was used for the following activities:
Cybersecurity researchers have warned of a supply chain compromise impacting WordPress plugin vendor BdThemes, prompting the content management systems (CMS) platform's plugins team to temporarily disable their downloads. "Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said. Supply chain compromises are especially dangerous because trust in a vendor’s distribution channel is abused to reach a much wider set of victims than a direct attack ever could. Beyond patching, organizations should inventory exposed services, disable unused functionality, and require multi-factor authentication wherever it can be deployed.

"Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said. "Instead, threat actors poisoned a static remote JSON data stream fetched by an administrative promotional banner component." Users visiting the listings for each of the aforementioned plugins on the WordPress plugins directory are displayed the message that they have been closed as of either August 7 or 8, 2026, and are not available for download pending a "full review." The issue, per the WordPress security company, is rooted in an internal component called Biggopti that's shipped along with the plugins. The system is designed to pull promotional banners from their API server and render them in the WordPress admin dashboard by fetching relevant JSON files from a DigitalOcean Spaces bucket.
Attacker-controlled instructions can make Atlassian's Rovo assistant collect Jira or Confluence data that a signed-in user can access, then send it to an outside server. Two security firms found that behavior independently, by different routes. Only one of those routes is confirmed closed. PromptArmor, an AI security firm, hid the instructions in content Rovo reads. It said an uploaded file was enough to make the assistant gather internal data and send it out through a URL request, with no separate approval step. The firm published on August 5, 2026 and said the chain still worked with Rovo's web-search option switched off. That bypass is single-sourced, and the report establishes the finding's status only on that date; a later remediation is not confirmed here. Varonis Threat Labs put the instructions in a link instead. It found that the rovoChatPrompt URL parameter would preload attacker instructions into Rovo Chat, so one click from an authenticated user was enough for Rovo to run them with that user's privileges and send the results to an attacker-controlled server.
WordPress has fixed a pre-authentication reflected cross-site scripting (XSS) flaw in its login screen that affects every version of the content management system. pwn.ai demonstrated how the flaw can be chained into PHP code execution on the server when a logged-in administrator interacts with an attacker-controlled page. Tracked as CVE-2026-64638 (CVSS score: 8.9), the high-severity The flaw has been cataloged as CVE-CVE-2026-64638, and technical details are now widely available, which means exploitation attempts often follow disclosure very quickly. Security teams should review their detection rules, keep threat-intelligence feeds current, and validate that incident-response runbooks are tested before an incident occurs.
WordPress has fixed a pre-authentication reflected cross-site scripting (XSS) flaw in its login screen that affects every version of the content management system. pwn.ai demonstrated how the flaw can be chained into PHP code execution on the server when a logged-in administrator interacts with an attacker-controlled page. Tracked as CVE-2026-64638 (CVSS score: 8.9), the high-severity vulnerability requires no attacker privileges. According to pwn.ai, which discovered the flaw and shared technical details with The Hacker News, the login-page XSS requires no authentication. Once a crafted username reaches the failed-login error page, the resulting JavaScript executes in the visitor's browser with no further interaction required on that page. The code-execution path requires a victim already logged in as an Administrator and explicit interaction with an attacker-controlled page. In pwn.ai's demonstration, that interaction is one ordinary click.
