Is this vulnerability remotely exploitable?

Yes, if an attacker can remotely submit or influence a skill archive that prompts.chat processes, they can potentially trigger arbitrary file writes on the target system. The actual exploitability depends on how archives are ingested (e.g., public upload vs. restricted interface).

What level of access does an attacker need to exploit this?

The attacker needs the ability to provide a crafted ZIP archive that the vulnerable component will extract. No shell or local account is required beyond whatever mechanism is used to upload or import the skill package.

What is the safest general fix pattern for this issue?

The safest approach is to sanitize and constrain all archive entry paths before writing: - Canonicalize paths - Enforce that they stay within a designated directory - Reject or ignore any entry that attempts to traverse out of that directory
