## Description

The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via campaign categories in all versions up to, and including, 2.9.1, due to insufficient input sanitization and output escaping. The categories of a campaign were stored as submitted instead of as category IDs, and were written unescaped into the hidden quick-edit data of the campaigns list. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts that execute when an administrator views the campaigns list.
