SonicWall Global Management System Hit by Critical RCE and Path Traversal Vulnerabilities
SonicWall has disclosed multiple critical vulnerabilities in its SonicWall Global Management System (GMS) management product and is urging customers to apply the newly released updates.
The company published security advisory SNWLID-2026-0011 on August 11, detailing six vulnerabilities that affect both the virtual appliance and Windows editions of GMS. The advisory assigns the highest severity rating of Critical to the issues.
In the Dispatcher Service, researchers identified CVE-2026-66147, which permits unauthenticated attackers to inject commands via specially crafted requests and execute arbitrary code remotely. The vulnerability received a CVSSv3 base score of 9.4.
A separate flaw, CVE-2026-66145, arises from insufficient validation during zip archive extraction. This path traversal issue allows remote attackers to read sensitive files or write arbitrary files to the system without authentication, earning a CVSSv3 base score of 9.1.
SonicWall has made patched versions available and recommends that all affected organizations update their installations as soon as possible to mitigate the risk of remote code execution.

Critical Vulnerabilities in PaperCut NG and PaperCut MF Exploited in the Wild
PaperCut Software has disclosed two serious vulnerabilities in its printing management solutions PaperCut NG and PaperCut MF. The issues were detailed in an advisory published on August 27, 2026, followed by emergency patches. Exploitation has already been confirmed in customer environments. CVE-2026-81578 stems from improper access controls in the web management interface, allowing unauthenticated remote changes to system settings. CVE-2026-82078 involves insecure dynamic class loading in database connections, enabling arbitrary Java bytecode execution with server privileges when combined with the first flaw. CVSS scores are 9.4 (Critical) and 8.8 (High) respectively, and both vulnerabilities have been added to CISA’s Known Exploited Vulnerabilities Catalog.
Positive Technologies Develops Dynamic Crawler for Single-Page Applications in PT BlackBox Scanner
Positive Technologies engineers have detailed the development of a dynamic crawler for their PT BlackBox DAST scanner to handle modern single-page applications built with frameworks such as React and Vue. The crawler must discover attack surface elements that only appear after user interactions because static parsing of initial DOM fails on SPAs where navigation occurs without URL changes. Key challenges include identifying interactive elements whose handlers are attached via JavaScript, detecting state changes after clicks or inputs, and managing combinatorial explosion of states caused by independent UI toggles. The team models the application as a labeled transition system and defines state equivalence using sets of 64-bit fingerprints of interactive elements rather than raw HTML similarity or URL values. This equivalence relation satisfies reflexivity, determinism from external observations, cheap hash-based comparison, slower growth than action count, and preservation of enabled actions across equivalent states. The approach allows the crawler to visit representatives of equivalence classes instead of every reachable state, keeping scans finite and practical within action budgets of several thousand interactions.
Over 8,300 Gitea Servers Remain Exposed to Remote Code Execution via CVE-2026-60004
Thousands of publicly accessible Gitea instances were still unpatched against CVE-2026-60004 as of late August 2026, leaving them open to remote command execution. The critical vulnerability combines abuse of the diffpatch endpoint with the ability to install and trigger attacker-controlled Git hooks, allowing unauthenticated attackers to run commands on the server. Exploitation requires only write access to a repository, which is often trivial due to default open user registration in many deployments. The issue was fixed in Gitea 1.27.1 released on July 27, 2026, and CISA added the flaw to its Known Exploited Vulnerabilities catalog with a remediation deadline of August 28 for U.S. federal agencies. In observed incidents, attackers used the access to deploy cryptocurrency miners inside Docker containers. A related authentication bypass affecting the official Docker image, CVE-2026-20896, was also noted when reverse-proxy headers such as X-WEBAUTH-USER are enabled.
Microsoft Defender Displays False 'Enable Virus Protection' Alerts on Windows Despite Active Real-Time Protection
Microsoft has confirmed a bug in Microsoft Defender that causes Windows to show persistent notifications urging users to enable virus protection even when the antivirus is already running with real-time protection active. The issue emerged after recent Defender updates and affects home users as well as enterprise environments running Windows 11 versions 23H2, 24H2, and 25H2, along with Windows 10 and Windows Server editions. Notifications appear at startup or during normal operation, ignore Do Not Disturb settings, and clicking them only opens the Windows Security app without resolving the alert. Microsoft is developing a fix to be released in a future Defender update but has not provided a timeline. Users are advised not to dismiss all such banners automatically, as similar messages could originate from malware, and should verify protection status through Windows Security or PowerShell commands. The problem stems from configuration errors introduced by the antivirus updates rather than specific Windows builds.
