Is this vulnerability remotely exploitable?

Yes, but indirectly. Exploitation occurs when a local user runs wlc against a malicious or compromised Weblate server that responds with crafted paths. The attacker does not need local access but must control or influence the server endpoint.

What level of access does an attacker need?

The attacker needs control over the Weblate instance (or equivalent ability to tamper with responses) that the wlc client communicates with. They do not need direct access to the client machine beyond the user's act of running wlc.

What is the safest general fix pattern?

The most robust fix is to strictly constrain all files written by wlc to a predefined download directory, normalize and canonicalize any path components, and reject any server-provided paths that resolve outside this directory or contain traversal patterns.
