CVE-2026-74888
Last modified
CVE-2026-74888 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
