CVE-2026-80204Network attack vector

Permission metadata disclosure via uncapped scope checks

Published Aug 26, 2026 · Updated Aug 26, 2026

Incorrect authorization in GetGrav Grav API plugin before 1.0.18 allows remote authenticated users to view out-of-scope page permissions. BlueprintController::injectSecurityTab() uses raw isSuperAdmin() and hasPermission() results without applying the API-key scope cap. A scoped API key tied to an account with broader rights is required; confirmed impact is permission-metadata disclosure, while write-time impact remains unverified.
