CVE-2026-74888 openssl_encrypt before 1.4.0 Non-Standard PBKDF2 Key Derivation

opensslencrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords...

CVE-2026-74871

The jahlives/openssl_encrypt PHP package before 1.4.6 has a KDF bypass: in sequential XOR composition mode the final stage cancels out, so attackers with local access can crack passwords at SHA-256 speed instead of the configured memory-hard KDF cost. CVSS 6.2 (MEDIUM, local). No in-the-wild expl...

CVE-2026-74871

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...
