CVE-2026-81704
HighCVSS 7.5Summary
openssl_encrypt before 1.4.9 uses weak key derivation in D-Bus CryptoService.EncryptFile, using unstretched SHA-256 instead of Argon2id. Attackers can perform offline password guessing against encrypted files much faster than documented.
Risk Assessment
The organization is exposed to rapid password cracking of encrypted files, potentially leading to disclosure of sensitive data.
Recommendation
Upgrade openssl_encrypt to 1.4.9 or later, which uses Argon2id for key derivation.
Original NVD description (English source)
openssl_encrypt versions before 1.4.9 contain a weak key derivation vulnerability in the D-Bus CryptoService.EncryptFile handler that uses unstretched SHA-256 instead of Argon2id. Attackers can perform offline password guessing against encrypted files roughly six to seven orders of magnitude faster than documented protection by exploiting the missing key stretching and hash rounds.
