{"id":"CVE-2026-56450","summary":"AIL Framework - Missing Rate Limiting Enables Brute-Force Attacks Against Two-Factor Authentication Codes","details":"AIL did not restrict repeated failed attempts to verify a two-factor authentication (OTP) code. An attacker who had reached the 2FA verification step, such as after successfully completing the password-authentication stage, could submit an unlimited number of OTP guesses. This could enable brute-force guessing of a valid code and bypass the intended second authentication factor, resulting in unauthorized account access.\n\n\nThe patch introduces per-user failed-OTP tracking, blocks verification after 30 failed attempts for one hour, clears the counter after a successful OTP verification, and provides administrator recovery actions to purge affected lockouts.","modified":"2026-08-12T03:51:46.443063996Z","published":"2026-06-22T13:02:30.320Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56450.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"6.8.0"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"CIRCL","cwe_ids":["CWE-307"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/56xxx/CVE-2026-56450.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56450"},{"type":"FIX","url":"https://github.com/ail-project/ail-framework/commit/d3a394fe68fd5aeee86f3a3c91d4a0350f91e974"},{"type":"PACKAGE","url":"https://github.com/ail-project/ail-framework"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ail-project/ail-framework","events":[{"introduced":"0"},{"fixed":"d3a394fe68fd5aeee86f3a3c91d4a0350f91e974"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v6.8","v6.7","v6.6","v6.1","v6.0.1","v6.0","v5.9","v5.8","v5.7","v5.5","v5.4","v5.3","v5.0","v4.1","v4.0","v3.7","v3.6","v3.5","v3.1","v3.0","v2.8","v2.7","v2.6","v2.5","v2.4","v2.3","v2.2","v2.1","v2.0","v1.8","v1.7","v1.6","v1.5","v1.3","v1.2","v1.1","v1.0","v0.90"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-56450.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"}]}
