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 contain a signature verification vulnerability in gpg_runner.verify_detached that accepts revoked and expired keys by only checking VALIDSIG status without inspecting REVKEYSIG, EXPKEYSIG, or gpg exit codes. Attackers holding compromised-then-revoked signing keys or expired project keys can bypass signature verification to execute malicious plugins in the host process.
