{"schemaVersion":3,"id":"CVE-2026-62669","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Grav Login Plugin adds login, basic ACL, and session wide messages to Grav. 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.

3.8.11.","dates":{"published":"2026-08-19T15:40:03.252Z","modified":"2026-08-19T18:18:46.380Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.4,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","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","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","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","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00501,"percentile":0.4172,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0.11499999999999995,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00386},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00501,"percentile":0.4172}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00386,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00501,"percentile":null},{"date":"2026-10-10T00:00:00.
