Description
The Permalink Manager Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in the admin URI Editor interface in all versions up to, and including, 2.5.3.3 due to insufficient output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in the admin Permalink Manager page that will execute whenever an administrator accesses the Permalink Manager page.
