Name of the Vulnerable Software and Affected Versions W3 Total Cache versions prior to 2.1.3

Description The issue allows high privilege users to inject JavaScript into certain CDN settings, which will be output in the page, leading to an authenticated Stored Cross-Site Scripting issue. This occurs because the settings are not properly sanitised or escaped.

Recommendations For versions prior to 2.1.3, update to version 2.1.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the CDN settings to minimize the risk of exploitation.
