HIGH 8.8

Grav API Plugin before 1.0.14 Missing Authorization

CVSS Score
8.8
EPSS Score
0.0%
EPSS Percentile
0th

The Grav API plugin (getgrav/grav-plugin-api, bundled with Grav's admin-next/API stack) before 1.0.14 fails to enforce the authorize requirement in MenubarController::executeAction(). While the GET /menubar/items listing endpoint correctly filters menubar items via userPassesAuthorize(), the POST /api/v1/menubar/actions/{plugin}/{action} endpoint only checks the baseline api.access permission and never evaluates the authorize field a plugin registered for that action. Any authenticated caller with api.access can therefore invoke a privileged menubar action directly, bypassing the intended authorization. No plugin bundled with core Grav currently registers a privileged authorize handler, so on a stock install the impact is latent; the flaw affects any first- or third-party plugin relying on the documented authorize semantics.
