GutenKit <= 2.5.0 - Authenticated (Contributor+) Arbitrary CSS Injection
The GutenKit plugin for WordPress is vulnerable to CSS Injection in all versions up to, and including, 2.5.0. This is due to missing capability check on the saving user before persisting CSS style settings to post meta and block attributes, and missing trust validation before rendering those settings as an inline stylesheet. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary CSS into pages served to site visitors, enabling defacement, interface redressing, and forcing external resource loads.
