Published Mar 25, 2025 · Updated Mar 25, 2025
Stored XSS in Mathieu Chartier WP-Advanced-Search before 3.3.9.3 allows remote authenticated users to execute script via plugin settings. The Text for search query setting accepts crafted attribute text, stores it, and later renders it on the Advanced Search page without output escaping. Administrator privileges are required to save the payload, and script execution occurs when another user visits and triggers Advanced Search, including when unfiltered_html is disabled in multisite.
