CVE-2026-81695
LowCVSS 3.3Summary
openssl_encrypt versions before 1.4.9 fail to escape attacker-controlled key_id values printed to stderr during decrypt auto-detection. Attackers can craft encrypted files with malicious key_id containing escape sequences to repaint terminal output and forge authenticity verification blocks.
Risk Assessment
Forged authenticity verification blocks could make users believe in the correctness of decryption of non-authentic data, potentially leading to confidentiality or integrity breaches.
Recommendation
Update openssl_encrypt to version 1.4.9 or later, which includes the fix for escaping key_id.
