CVE-2026-72833 is a privilege escalation vulnerability in the Grav API plugin (getgrav/grav-plugin-api) affecting versions 1.0.6 through 1.0.11. The flaw arises from authorization logic on four write endpoints in GroupsController, AccountsConfigController, PreferencesController, and DashboardWidgetController. These endpoints use an isSuperAdmin() early-return path for authorization and, in that path, do not invoke requirePermission(), which is the enforcement point for API key scope restrictions. As a result, a scoped API key minted on a super-admin account can bypass its declared scope cap on those endpoints. Even a nominally read-only key can invoke super-admin-only write operations, including modifying group ACL mappings in ways that can grant super-admin privileges to arbitrary accounts. The issue was fixed in version 1.0.13.

A privilege escalation vulnerability in the Grav API plugin where a scoped API key created on a super-admin account can bypass scope restrictions on certain super-admin-gated write endpoints, allowing read-only scoped keys to perform privileged write actions and potentially grant super-admin privileges to arbitrary accounts.
