{"apiVersion":"1.0","identifier":"CVE-2026-62669","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. This issue is fixed in version 3.8.11.","publishedAt":"2026-08-19T16:18:19","lastModifiedAt":"2026-08-19T19:17:22","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62669","cvssScore":7.4,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","epssProbability":0.00386,"riskScore":0.77,"affectedProduct":"Grav Login Plugin","affectedVersions":"<3.8.11","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62669","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62669","en":"https://www.redsauce.net/en/cves/CVE-2026-62669","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62669","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62669","de":"https://www.redsauce.net/de/cves/CVE-2026-62669","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62669","el":"https://www.redsauce.net/el/cves/CVE-2026-62669"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62669"}}
