CVE-2026-81701
CriticalCVSS 9.8Summary
openssl_encrypt before 1.4.9 uses a denylist to identify trusted built-in plugins, allowing unsigned plugins in top-level plugins/ directories and unknown subdirectories to bypass signature verification. Attackers can place malicious unsigned plugins to achieve arbitrary code execution in the CLI process with access to passwords and cryptographic keys.
Risk Assessment
An attacker can execute arbitrary code in the CLI process, gaining access to sensitive data such as passwords and cryptographic keys.
Recommendation
Update openssl_encrypt to version 1.4.9 or later, which includes the fix for plugin signature verification.
