CVE-2026-62666
Grav API Plugin: non-super api.users.write manager -> super-admin via createApiKey (incomplete fix of CVE-2026-59190); + 2FA strip of super
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.

8.7
grav-plugin-api < 1.0.6 Privilege Escalation via createApiKey
grav-plugin-api before 1.0.6 fails to validate super-admin status in createApiKey, generate2fa, and disable2fa endpoints, allowing non-super api.users.write managers to escalate to super-admin. Attackers can mint API keys bound to super-admin accounts or strip 2FA from super-admin users to achieve full instance takeover.
