AI-suggested

Users should upgrade to jahlives openssl_encrypt version 1.4.0 or later once available, as versions before 1.4.0 are affected. Until a patch is confirmed, avoid using legacy encrypted files protected by this vulnerable key derivation method.

Description

openssl_encrypt 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 protecting legacy encrypted files compared to standard PBKDF2 implementations.
