CVE-2026-109590

The Tour Booking Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'width', 'height' and 'zoom' shortcode attributes of the [ttbm-hotel-map] shortcode in versions up to, and including, 2.3.6 This is due to insufficient input sanitization and output escaping on user supplied attributes in the ttbm hotel map shortcode() function, which concatenates the raw attribute values into double-quoted HTML attributes of an tag. 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.
