Hydra Booking < 1.1.39 - Authenticated (Hydra host+) Stored Cross-Site Scripting

Description

The Hydra Booking plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.1.38 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with hydra host-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
