Booking Calendar < 10.14.2 - Authenticated (Contributor+) Stored Cross-Site Scripting

Description

The Booking Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via settings in all versions up to, and including, 10.14.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
