WPeMatico RSS Feed Fetcher vulnerabilities

The WPeMatico RSS Feed Fetcher WordPress plugin before 2.8.26 does not sanitise and escape one of its campaign configuration fields when a certain feature is enabled, which allows users with the Contributor role and above to perform Stored Cross-Site Scripting attacks that execute in the session of any higher-privileged user who later views the campaign.

The WPeMatico RSS Feed Fetcher WordPress plugin before 2.8.26 does not sanitize and escape content it retrieves from a user-supplied source before rendering it, which could allow users such as contributors to perform Stored Cross-Site Scripting attacks against higher-privileged users who review the campaign.

The WPeMatico RSS Feed Fetcher plugin versions up to 2.8.17 are vulnerable to unauthenticated Cross Site Scripting (XSS). An attacker can inject malicious script without authentication.
