CVE-2026-75835 · Severity: medium · CVSS 4.3 · Published 2026-08-18

Grav's API plugin is used to manage content and administrative functions via authenticated API keys. This vulnerability allows an attacker with a restricted API key (issued on a privileged account) to bypass scope restrictions and view UI metadata, item definitions, and configuration details they should not have access to. While read-only, this information disclosure could expose sensitive operational details and aid further attacks.

## Technical details

The userPassesAuthorize() function in AbstractApiController.php fails to validate API key scopes when determining authorization for gated UI items. It checks the underlying user account's raw super-admin flag and ACL permissions without consulting the calling request's declared api_key_scopes. An attacker with a scoped API key (e.g., restricted to ["api.access", "api.pages.read"]) minted on a super-admin account can bypass scope restrictions to access authorize-gated sidebar/menubar/widget items and users-list metadata that the key's declared scope should deny. The vulnerability affects six call sites across multiple controllers (SidebarController, FloatingWidgetController, EditorButtonsController, MenubarController, UsersController). Exploitation requires a valid API key and is read-only; patches are available in version 1.0.14.
