{"id":"CVE-2026-80203","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80203","summary":"The getgrav/grav-plugin-api plugin before 1.0.18 does not enforce API-key scope in the requireNotSuperTarget() function in UsersController.php across seven sensitive user-management…","details":"The getgrav/grav-plugin-api plugin before 1.0.18 does not enforce API-key scope in the requireNotSuperTarget() function in UsersController.php across seven sensitive user-management endpoints. The check uses isSuperAdmin() on the acting account rather than verifying whether the specific API key carries super authority (via isSuperWithinScope()). As a result, an API key scoped below full super authority but belonging to a super-admin account can act against other super-admin accounts—disabling their 2FA, deleting their avatar, minting new API keys under their identity, or deleting their existing API keys.","published":"2026-08-26T11:16:39.647","modified":"2026-08-26T11:16:39.647","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/getgrav/grav/security/advisories/GHSA-94q7-vrqr-cx5v"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/grav-before-1.0.18-authentication-bypass-via-scoped-api-key"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-26T11:16:39.647"}}
