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.
