Is this vulnerability remotely exploitable?

Yes. Remote exploitation is possible if an attacker can influence the arguments passed to the `sendMediaFeishu` tool—either directly through user input or indirectly via prompt injection or compromised upstream data that the model incorporates into tool calls.

Does an attacker need local access to the server?

No direct OS-level access is required. The attack relies on the OpenClaw process itself having read access to local files; the attacker only needs a way to drive the assistant to call `sendMediaFeishu` with attacker-chosen `mediaUrl` values.

What is the safest general fix pattern?

The safest pattern is to treat `mediaUrl` strictly as a reference to remote or pre-approved media, enforce a whitelist of protocols or storage backends, and ensure any local file reading (if absolutely necessary) goes through a constrained helper that enforces a fixed root directory, canonicalization, and strict validation.
