Lightbox & Modal Popup WordPress Plugin – FooBox <= 2.7.34 - Authenticated (Author+) Stored Cross-Site Scripting

The Lightbox & Modal Popup WordPress Plugin – FooBox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via image alternative texts in all versions up to, and including, 2.7.34 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
