Executive Summary

The vulnerability exists in the Permalink Manager Lite plugin for WordPress, affecting all versions up to and including 2.5.3.3. It is a Stored Cross-Site Scripting (XSS) flaw that occurs via post titles in the admin URI Editor interface. This happens because the plugin does not properly escape output, allowing authenticated users with Contributor-level access or higher to inject arbitrary web scripts. These scripts execute whenever an administrator accesses the Permalink Manager page.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access or above to inject malicious scripts into the admin Permalink Manager page. When an administrator views this page, the injected scripts execute, potentially leading to unauthorized actions such as stealing administrator session tokens, performing actions on behalf of the administrator, or compromising the integrity of the WordPress site.
