Modula Image Gallery <= 2.10.1 - Authenticated (Contributor+) Stored DOM-Based Cross-Site Scripting via FancyBox 5 JavaScript Library

The Modula Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's bundled FancyBox JavaScript library (versions <= 5.0.36) 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.
