CVE-2026-74874: Jahlives OpenSSL Encrypt

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

openssl_encrypt versions before 1.4.0 use Python's non-cryptographic random module for steganographic pixel selection in the generate_pseudorandom_sequence function. Attackers who know the password can recover the Mersenne Twister state from approximately 624 outputs and predict pixel locations containing hidden data for extraction.

Affected products
