Travelly <= 2.3.6 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'width', 'height', and 'zoom' Shortcode Attributes

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 <iframe> 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.
