{"id":"CVE-2026-80203","state":"PUBLISHED","title":"Grav before 1.0.18 Authentication Bypass via Scoped API Key","description":"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.","publishedAt":"2026-08-26T10:28:12.996Z","updatedAt":"2026-08-28T22:48:35.508Z","severity":{"score":9.3,"label":"Critical","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["getgrav grav"],"affected":[{"vendor":"getgrav","product":"grav","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"1.0.18","versionType":"semver"},{"version":"1.0.18","status":"unaffected","versionType":"semver"}]}],"references":["https://github.com/getgrav/grav/security/advisories/GHSA-94q7-vrqr-cx5v","https://www.vulncheck.com/advisories/grav-before-1.0.18-authentication-bypass-via-scoped-api-key"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/80xxx/CVE-2026-80203.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-80203","state":"PUBLISHED","datePublished":"2026-08-26T10:28:12.996Z","dateUpdated":"2026-08-28T22:48:35.508Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-25T23:15:39.155Z"},"containers":{"cna":{"title":"Grav before 1.0.18 Authentication Bypass via Scoped API Key","descriptions":[{"lang":"en","value":"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.
