Is this vulnerability remotely exploitable?

Yes. Any user who can authenticate to the File Browser instance and reach the TUS DELETE endpoint over the network can attempt to exploit the issue, provided they have Create permission within a scope.

What level of access does an attacker need?

The attacker must have a valid account with at least Create permission in a given directory or workspace, but without Delete permission. The flaw allows them to bypass the intended restriction and delete files and directories within that scope.

What is the safest general fix pattern?

The most robust fix is to enforce explicit, per-action authorization for delete operations, validating a dedicated Delete permission before performing any removal. Centralizing permission checks and refusing to infer Delete from Create or other capabilities helps ensure consistency and reduces the chance of future bypasses.
