{"id":"CVE-2026-72833","state":"PUBLISHED","title":"Grav 1.0.6 through 1.0.11 Privilege Escalation via Scoped API Keys","description":"The Grav API plugin (getgrav/grav-plugin-api) versions >= 1.0.6 and <= 1.0.11 contain a privilege escalation vulnerability. A scoped API key minted on a super-admin account bypasses its declared scope cap on four isSuperAdmin()-gated write endpoints (in GroupsController, AccountsConfigController, PreferencesController, and DashboardWidgetController). These endpoints authorize via a super-admin early-return that never invokes requirePermission()—the sole enforcement point of the scope cap—so a 'read-only'-scoped key (e.g. api.pages.read) can perform super-only write operations, including rewriting group ACL maps to grant super-admin privileges to arbitrary accounts. A leaked or delegated read-only CI/monitoring key can therefore gain full super-admin write capability. Fixed in 1.0.13.","publishedAt":"2026-08-14T11:35:39.243Z","updatedAt":"2026-09-30T17:20:22.525Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["getgrav grav-plugin-api"],"affected":[{"vendor":"getgrav","product":"grav-plugin-api","defaultStatus":"unaffected","versions":[{"version":"1.0.6","status":"affected","lessThanOrEqual":"1.0.11","versionType":"semver"}]}],"references":["https://github.com/getgrav/grav/security/advisories/GHSA-jqgq-v53x-x99g","https://www.vulncheck.com/advisories/grav-through-privilege-escalation-via-scoped-api-keys"],"weaknesses":["CWE-269"],"ingestedAt":"2026-10-29T20:12:58.252Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/72xxx/CVE-2026-72833.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-72833","state":"PUBLISHED","datePublished":"2026-08-14T11:35:39.243Z","dateUpdated":"2026-09-30T17:20:22.525Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-08-10T15:13:41.486Z"},"containers":{"cna":{"title":"Grav 1.0.6 through 1.0.11 Privilege Escalation via Scoped API Keys","descriptions":[{"lang":"en","value":"The Grav API plugin (getgrav/grav-plugin-api) versions >= 1.0.6 and <= 1.0.11 contain a privilege escalation vulnerability.
