Technical details

The vulnerability is a reflected cross-site scripting (XSS) flaw in the king_addons_filter_grid_posts AJAX action. The plugin accepts user-supplied grid settings, specifically the overlay_animation parameter, and reflects it unsanitized into an HTML class attribute. The AJAX endpoint is reachable without authentication and uses a nonce that is publicly exposed in pages containing the Posts Grid widget. An attacker can craft a malicious POST request with an injected payload (e.g., `"><img src=x onerror=alert()>`) that breaks out of the class attribute and executes arbitrary JavaScript in the victim's browser. The vulnerability was patched in version 51.1.76.
