{"apiVersion":"1.0","identifier":"CVE-2026-62666","description":"Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site-s content. Prior to 1.0.6, Grav API plugin UsersController::createApiKey(), generate2fa(), and disable2fa() omit the accessGrantsSuper() target check used by sibling user mutation endpoints. A non-super account with api.users.write can mint an API key bound to an access.api.super target through requireApiKeyPermission(), obtain the target-s full privileges because key scopes are not enforced, and create persistent super-administrator access; the same missing check also permits rotating or disabling the target-s two-factor authentication. This issue is fixed in version 1.0.6.","publishedAt":"2026-08-19T16:18:19","lastModifiedAt":"2026-08-21T20:16:38","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62666","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00426,"riskScore":0.91,"affectedProduct":"Grav API Plugin","affectedVersions":"<1.0.6","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62666","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62666","en":"https://www.redsauce.net/en/cves/CVE-2026-62666","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62666","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62666","de":"https://www.redsauce.net/de/cves/CVE-2026-62666","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62666","el":"https://www.redsauce.net/el/cves/CVE-2026-62666"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62666"}}
