Responsive Lightbox & Gallery WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Responsive Lightbox & Gallery WordPress plugin, affecting versions prior to 2.5.2. The issue arises because the plugin's Swipebox library does not properly validate and escape title attributes before displaying them on pages or posts. This flaw enables users with contributor roles and above to execute stored cross-site scripting attacks.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
