Exploited in the last 30 days

Grav API Plugin is a RESTful API for Grav CMS that provides full headless access to your site's content. Prior to 1.0.6, Grav API plugin UsersController::createApiKey(), generate2fa(), and disable2fa() omit the accessGrantsSuper() target check used by sibling user mutation endpoints. A non-super account with api.users.write can mint an API key bound to an access.api.super target through requireApiKeyPermission(), obtain the target's full privileges because key scopes are not enforced, and create persistent super-administrator access; the same missing check also permits rotating or disabling the target's two-factor authentication. This issue is fixed in version 1.0.6.
