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 verify that a user running a feed campaign is permitted to publish content or to attribute posts to another account, allowing users with contributor-level access and above to publish posts live and set any registered user, including an administrator, as the post author.
