Advisory
Source description from Wordfence Intelligence, credited to fcc.
The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.10.7. This is due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
