CVE-2026-74874
Last modified
CVE-2026-74874 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
