## Description

The Booking Package plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the plugin's 'booking_package' shortcode in all versions up to, and including, 1.7.29 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
