CyberRota Analysis
AI-GeneratedThe GutenKit WordPress plugin prior to version 2.5.1 is vulnerable due to inadequate validation and escaping of style settings, enabling users with Contributor roles and above to inject arbitrary CSS into publicly served pages. The primary impact includes potential defacement and interface manipulation, though JavaScript execution is not possible at this role, limiting the severity of the attack. WordPress site administrators and developers should prioritize this vulnerability to prevent unauthorized styling changes and maintain the integrity of their user interfaces.
Original NVD Description
The GutenKit WordPress plugin before 2.5.1 does not validate or escape style settings saved against a post before using them to build the CSS it outputs on the front end, allowing users with the Contributor role and above to inject arbitrary CSS into pages served to other users and to anonymous visitors. JavaScript execution is not possible at that role, so the impact is limited to defacement, interface redressing and forcing external resources to load.
