What fixes it

  • 2.8.27WPeMatico 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 2.8.27 does not perform a capability check or validate the destination of a user-supplied feed URL before fetching it server-side, allowing users with contributor-level access and above to make the server issue requests to internal-only resources and read the responses back.
