Administrator XSS via unescaped PHP_SELF
Published Oct 16, 2023 · Updated Apr 23, 2025
Cross-site scripting in WP Matterport Shortcode before 2.1.7 allows remote attackers to execute script in an administrator's browser via a crafted URL. The plugin places the PHP_SELF server variable directly into HTML attributes without escaping, allowing reflected script payloads to execute when a logged-in administrator opens the URL. Exploitation requires administrator interaction with the crafted link and can alter page content or perform actions available to that administrator.
