OpenSSL is a security standard that protects most of the internet, and cybersecurity researchers have recently discovered vulnerabilities in the standard that have been lying undetected for decades. The Cybersecurity team at Aisle reported in a blog post that it found 12 CVEs in OpenSSL's codebase and has issued fixes for all 12 CVEs. All of these vulnerabilities were only discovered with the help of AI-powered security tools.
All 12 CVEs include high, moderate, and low-severity variants. CVE-2025-15467 is a Stack Buffer Overflow vulnerability that can enable attackers to execute remote commands under certain conditions. CVE-2025-11187 is a vulnerability that takes advantage of a missing validation that could trigger a stack-based buffer overflow. The former is considered high severity, while the latter is considered moderate.
