Summary

The Tournamatch WordPress plugin before 4.7.1 does not validate or restrict the path of a previously stored profile or team image before deleting it when a new image is uploaded, allowing users with a role as low as Subscriber to delete arbitrary files on the server, such as wp-config.php, which can lead to a full site takeover.
