Prior to 3.8.11, the Grav Login plugin login.regenerate2FASecret task checks only that the pending-session user exists rather than requiring $user->authorized. After submitting a victim's correct password, an attacker can invoke taskRegenerate2FASecret() during the pending TOTP challenge, overwrite twofa_secret, read the replacement secret from the response, calculate a valid code, and complete authentication without the victim's second factor. This issue is fixed in version 3.8.11.","published":"2026-08-19T16:18:19.460","modified":"2026-08-19T16:18:19.460","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":{"url":"https://github.com/getgrav/grav-plugin-login/commit/5d1b722298cb947d8f434025d121b99152a2c630","label":"getgrav/grav-plugin-login@5d1b722"},"references":[{"type":"WEB","url":"https://github.com/getgrav/grav-plugin-login/commit/5d1b722298cb947d8f434025d121b99152a2c630"},{"type":"WEB","url":"https://github.com/getgrav/grav-plugin-login/releases/tag/3.8.11"},{"type":"WEB","url":"https://github.com/getgrav/grav/security/advisories/GHSA-7mgc-c7pq-3rr3"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T16:18:19.460"}}
