Stored XSS via unescaped URL Prefix setting
Published May 29, 2024 · Updated Aug 9, 2024
Stored XSS in Fumiki Takahashi Gianism 5.1.0 and earlier allows remote authenticated users to execute script through the URL Prefix setting. The settings handler stores the URL Prefix value without sanitizing it and later renders it without output escaping in the WordPress administration interface. Administrator-level access is required, and script execution occurs when a user loads the affected settings view even when unfiltered_html is disabled.
