## Description

The Admin Management Xtended plugin for WordPress is vulnerable to Stored Cross-Site Scripting via post titles in all versions up to, and including, 2.5.3. This is due to insufficient output escaping in the inline title edit feature: the rendered post title is read back from the posts/pages list and concatenated unescaped into an inline onclick attribute, and then into the HTML of the title edit input. This makes it possible for authenticated attackers with contributor-level access and above to inject arbitrary web scripts into a post title. The scripts run when an editor or administrator views or interacts with the posts or pages list.
