Name of the Vulnerable Software and Affected Versions: The Gallery Blocks with Lightbox plugin for WordPress versions up to, and including, 3.2.1

Description: The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows authenticated attackers with Contributor-level access and above to inject arbitrary web scripts in pages via the galleryID and className parameters. The injected scripts will execute whenever a user accesses an injected page.

Recommendations: For versions up to, and including, 3.2.1, update to a version that addresses the insufficient input sanitization and output escaping issue to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting access to the galleryID and className parameters to minimize the risk of exploitation.
