WordPress Fan Page Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Fan Page plugin for WordPress, affecting all versions through 1.0.1. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into pages. These scripts are executed when users access the compromised pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
