CVE-2026-81700
openssl_encrypt before 1.4.9 GPG Signature Verification Bypass
opensslencrypt versions before 1.4.9 contain a signature verification vulnerability in gpgrunner.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.
