Background
WordPress is a popular weblog manager used for creating and managing websites. It provides a user-friendly interface for content creation and customization. The package 'wordpress' in Debian version 6.0 (lenny) is affected by multiple vulnerabilities, including two Cross-Site Scripting (XSS) bugs and one potential information disclosure issue.
Vulnerability Detail
The first vulnerability, identified as CVE-2011-0700, occurs when input passed via the post title during Quick Edit or Bulk Edit actions, and via the post_status, comment_status, and ping_status parameters, is not properly sanitized. This can lead to the execution of malicious scripts or unauthorized disclosure of sensitive information. Additionally, certain input passed via tags in the tags meta-box is also not properly sanitized, posing a similar risk.
