Is this vulnerability remotely exploitable?

Yes, in deployments where file upload endpoints are reachable over the network and do not require authentication. An attacker who can send crafted uploads to such endpoints may influence where files are written on remote servers.

Does an attacker need credentials to exploit this?

Not necessarily. Exploitation does not require n8n user credentials if the vulnerable upload endpoints and associated workflows are unauthenticated. If endpoints are protected by authentication, an attacker would first need valid access or another way to bypass those controls.

What is the safest general fix pattern for affected workflows?

The most robust pattern is to completely decouple user input from remote file paths: define fixed, server-controlled directories for SSH uploads, normalize filenames, and insert explicit validation steps in the workflow that reject or rewrite any unsafe path components before invoking the SSH node.
