The Tourfic – AI Powered Travel Booking, Hotel Booking & Car Rental plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via unfiltered_html Grant to Customer Role in all versions up to, and including, 3.0.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires WooCommerce to be active, but since the customer role is freely self-registerable without admin approval, exploitation is effectively possible by any unauthenticated visitor who registers a WooCommerce account. While the plugin's own listing-page templates sanitize output with wp_kses_post(), the stored payload is returned unsanitized via the unauthenticated GET /wp-json/wp/v2/comments REST endpoint (content.rendered) and post/comment RSS feeds, exposing any headless client, feed reader, or third-party widget that renders comment content.
