## Description

The WPeMatico RSS Feed Fetcher plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the campaign log in all versions up to, and including, 2.9. This is due to insufficient sanitization and output escaping of log lines that quote titles and addresses read from feeds, which were output raw in the campaign log viewer and on the debug page. This makes it possible for unauthenticated attackers who control a feed that a campaign fetches to inject arbitrary web scripts that execute when an administrator views the campaign log.
