Because plugin/API/set.json.php?APIName=login_code can be called without authentication, it also serves as an oracle for the server's exact microtime. An unauthenticated remote attacker who guesses a valid, unexpired code (codes expire after 10 minutes) can redeem it at plugin/API/get.json.php?APIName=login_code to obtain the target account's email address and a User::getUserHash(users_id, '+1 year') value, a credential accepted in place of the account password for one year, resulting in account takeover. No patched version is available.","published":"2026-09-17T12:18:30.290","modified":"2026-09-17T12:18:30.290","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-v65f-hc7x-wj62"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/avideo-weak-prng-activation-code-authentication-bypass"},{"type":"WEB","url":"https://github.com/WWBN/AVideo/security/advisories/GHSA-v65f-hc7x-wj62"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T12:18:30.290"}}
