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.","published":"2026-08-17T11:16:43.523","modified":"2026-08-17T11:16:43.523","cvss":{"score":0,"severity":"NONE","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-cx72-m6xj-3vf6"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-insecure-random-import-in-pqc-module"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-17T11:16:43.523"}}
