Answer in brief
CVE-2026-74889 records a Unknown severity vulnerability in openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF. The current sources do not mark it as known exploited. The current feed maps jahlives/openssl_encrypt (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
