CVE-2026-72833
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
Summary
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.
