Description
The Portfolio Gallery – Image Gallery Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via gallery image titles in versions 2.1.5 up to, and including, 2.2.0 due to insufficient input sanitization and output escaping in the built-in lightbox, which inserts the image title (and, when enabled, the image description) into the page as HTML. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts into gallery images that will execute whenever a user opens the image in the lightbox.
