Description
The vulnerability allows a remote attacker to delete arbitrary files and directories within their scope.
The vulnerability exists due to improper access control in the TUS DELETE endpoint when handling DELETE requests to /api/tus/{path}. A remote attacker can send a specially crafted sequence of TUS requests to delete arbitrary files and directories within their scope.
Exploitation requires a multi-user deployment where deletion is restricted for some users, and the issue can be triggered by initiating a TUS upload for the target path before issuing the DELETE request.
