Use of Password Hash With Insufficient Computational Effort

Overview openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files Affected versions of this...

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 openssl_encrypt before 1.4.6 KDF Bypass via Sequential-XOR

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...
