Name of the Vulnerable Software and Affected Versions Firelight Lightbox versions prior to 2.3.24

Description Insufficient input sanitization and output escaping allow users with contributor-level access and above to inject arbitrary web scripts. This occurs because image attribute values are not properly escaped before being processed in the browser, leading to Stored Cross-Site Scripting (XSS), where scripts execute when another user views or previews the affected content.

Recommendations Update to version 2.3.24 or later.
