What fixes it

  • 2.8.26WPeMatico RSS Feed FetcherCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

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.
