AI-suggested
A fix is available in jahlives openssl_encrypt version 1.4.0 and later. Users should upgrade to version 1.4.0 or newer to mitigate this vulnerability. No vendor advisory content was provided, but the presence of a fixed version indicates an official fix is available.
Description
openssl_encrypt 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.
