CVE-2026-74887 PUBLISHED

openssl_encrypt before 1.4.0 Insecure Random Import in PQC Module

Assigner: VulnCheck
Reserved: 17.08.2026 Published: 17.08.2026 Updated: 17.08.2026

openssl_encrypt before 1.4.0 imports Python's non-cryptographic 'random' module (Mersenne Twister PRNG) at line 15 of openssl_encrypt/modules/pqc.py. No direct calls to random.* were present in the code, so no cryptographic operation is currently affected; however, the import creates a hazard that future code could inadvertently use random.randint() instead of a cryptographically secure alternative (secrets/os.urandom), producing predictable values since the Mersenne Twister state can be recovered from approximately 624 outputs. Fixed by removing the import in 1.4.0.
