CVE-2026-81718 openssl_encrypt before 1.4.9 Weak Cryptographic Parameters

opensslencrypt versions before 1.4.9 use under-parameterized PBKDF2-HMAC-SHA256 with only 100,000 iterations to protect PQC keyfile private keys and 10,000 iterations for dual-encryption file-password verification. Attackers who obtain keyfiles or encrypted files can brute-force wrapping password...

CVE-2026-81704 openssl_encrypt before 1.4.9 Weak Key Derivation via D-Bus

opensslencrypt 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 faste...

CVE-2026-81704

openssl_encrypt versions before 1.4.9 contain a weak key derivation vulnerability in the D-Bus CryptoService.EncryptFile handler. The affected code uses unstretched SHA-256 instead of Argon2id , omitting key stretching and hash rounds. This allows attackers to perform offline password guessing ag...

CVE-2026-81689

openssl_encrypt versions before 1.4.9 derive the remote-pepper wrap key using unsalted HKDF-SHA256 or bare SHA-256 of the password, resulting in identical keys across all users and files. An attacker with access to wrapped pepper blobs can precompute a single dictionary table and perform fleet-wi...
