The Starboard Suite Reservation Calendars plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcode attributes in the [starboard-suite-lightbox] shortcode in all versions up to, and including, 3.1.4 due to insufficient input sanitization and output escaping. 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.
