Summary

The Tournamatch WordPress plugin before 4.7.1 does not validate or restrict the path of a stored profile or team image before deleting it when a new image is uploaded. This external control of a file path (CWE-73) lets users with a role as low as Subscriber delete arbitrary files on the server, such as wp-config.php. An authenticated attacker with low privileges can cause a full site takeover, and a public exploit is linked in the references.
