This allows unused OTPs to remain valid indefinitely, presenting an opportunity for malicious actors to conduct brute force attacks by repeatedly guessing the OTP.\n\nThe absence of automatic expiration for OTPs grants attackers an unlimited timeframe to attempt guessing the correct code. A successful brute force attack can lead to an MFA bypass, resulting in the unauthorized takeover of a user's account and compromising the security and privacy of both the individual and the system.","published":"2026-10-08T01:16:32.000Z","lastModified":"2026-10-08T17:17:11.000Z","status":"Deferred","sourceIdentifier":"ed10eef1-636d-4fbe-9993-6890dfa878f8","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-613"],"affected":[],"epss":{"score":0.00254,"percentile":0.16763,"date":"2026-10-26","history":[{"date":"2026-10-08","score":0.00254,"percentile":0.15521}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.25%).
