CVE-2026-15464
WP Hotel Booking <= 2.3.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'widget_search' Shortcode Attribute
Description
The WP Hotel Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'widget_search' Shortcode Attribute in all versions up to, and including, 2.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is only exploitable on browsers where access keys can be used as the payload is stored in a hidden attribute.
