CVE-2026-74889 openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF

opensslencrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks...

CVE-2026-74889

The openssl_encrypt library (PHP package) before version 1.4.0 uses HKDF with no salt and a static info parameter in its key normalization functions, producing deterministic, low-entropy derived keys. Attackers with identical inputs can predict derived keys, weakening cryptographic security again...

Security Bulletin: Weak Cryptographic Key Derivation Exposed All Stored Credentials

Summary A critical vulnerability in the credential encryption system allowed attackers to decrypt all stored API keys, database passwords, and OAuth tokens. The system used Python's non-cryptographic Mersenne Twister PRNG seeded with the SECRETKEY to derive Fernet encryption keys for credentials...
