A serious security vulnerability in SonicWall Secure Mobile Access (SMA) 1000 appliances has been exploited by attackers shortly after it was made public. This flaw, identified as CVE-2026-102255, has a maximum severity score of 10.0 and involves pre-authenticated server-side request forgery (SSRF), which could enable remote attackers to manipulate the appliance into making unauthorized requests. SonicWall users are at risk, as the vulnerability has already seen 135 exploitation attempts. This situation underscores the urgency for affected organizations to act quickly to secure their systems and protect sensitive data from potential breaches.
Researchers from Northwestern University conducted a study on AI coding tools, specifically testing how well they could handle real security bugs. They analyzed 112 actual vulnerabilities and found that even when a patch eliminated a crash, a significant number of these patches—about one-third from Claude Opus 4.7—still failed to meet the tests set by project maintainers. This raises concerns for developers considering AI tools for vulnerability patching, as relying on AI could lead to unresolved issues in security checks. The findings suggest that while AI can help in addressing some vulnerabilities, it may not fully align with the quality standards necessary for effective security management, which could leave systems at risk.
The article discusses ongoing concerns around the FortiBleed vulnerability, which remains active and poses risks to numerous organizations. This vulnerability affects Fortinet's products, particularly those related to their FortiOS and FortiProxy systems.
