Name of the Vulnerable Software and Affected Versions The Responsive Lightbox & Gallery plugin for WordPress versions up to, and including, 2.4.7

Description The issue is related to Stored Cross-Site Scripting via file uploads due to insufficient input sanitization and output escaping, affecting the "rl upload image" AJAX endpoint. This allows authenticated attackers with Author-level access and above to inject arbitrary web scripts in pages that will execute whenever a user accesses the 3gp2 file.

Recommendations For versions up to, and including, 2.4.7, update the plugin to the latest patched version immediately to resolve the issue. As a temporary workaround, consider restricting access to the "rl upload image" AJAX endpoint until a patch is available. Additionally, restricting file uploads to only necessary users can help minimize the risk of exploitation.
