## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in the Magazine Grid and Taxonomy widgets' "Select Styling" settings. The vulnerable component fails to escape HTML special characters before rendering the setting value in an HTML class attribute. An attacker with Contributor-level access or above can craft a malicious payload (e.g., zz" onmouseover="alert(document.domain)" data-ka="X) that bypasses the select control's option validation and saves to the database. When the affected page is viewed, the payload breaks out of the class attribute context and executes arbitrary JavaScript in the visitor's browser. No authentication bypass is required for exploitation—only a valid Contributor account and network access to the WordPress admin interface. Patch available in version 51.1.77.
