Critical (9.3) in jahlives openssl encrypt. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in openssl-encrypt 1.4.9.
openssl_encrypt versions before 1.4.9 use 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 following documented installation paths to achieve arbitrary code execution in the CLI process with access to passwords and cryptographic keys.
