Photonic Gallery & Lightbox <= 3.21 - Authenticated Stored XSS via Lightbox Caption

Title source: llm

Description

The Photonic Gallery & Lightbox for Flickr, SmugMug & Others plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's lightbox functionality in all versions up to, and including, 3.21 due to insufficient input sanitization and output escaping on user supplied caption attribute. 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 the injected page.
