Short explanation
The W3 Total Cache plugin for WordPress up to version 2.10.7 is vulnerable to Stored Cross-Site Scripting via the comment parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts into pages.
This vulnerability allows unauthenticated attackers to execute arbitrary web scripts on target web pages. It specifically impacts environments where a Pro license became inactive while Disk Enhanced page caching remains configured.
What should be done?
- Follow vendor advisories and monitor for official updates
- Review plugin configurations and page caching settings

Show the technical text from the sources
The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 2.10.7 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. Exploitation requires that a Pro license was previously active with REST caching enabled and has since become inactive while Disk Enhanced page caching remains configured, and that the attacker holds a previously approved commenter identity.
