CVE-2026-75835
Grav API plugin (getgrav/grav-plugin-api) before 1.0.14 contains a missing authorization vulnerability in userPassesAuthorize() (AbstractApiController.php). The function fails to consult the calling request's API key scopes, relying instead on the account's raw super-admin flag and ACL grants. As a result, an authenticated attacker holding a scoped API key minted on a privileged account can bypass their declared scope restrictions to access authorize-gated UI metadata and item definitions (sidebar/menubar/widget items and users-list columns/row-actions/filter-tabs) that their key scope should deny, resulting in information disclosure.
