Is this vulnerability remotely exploitable?

Yes, in environments where Synology Chat is reachable, any user who can send messages through the Synology Chat instance connected to OpenClaw may be able to exploit the issue, provided the affected dmPolicy configuration is in place.

What level of access does an attacker need?

The attacker needs Synology Chat sender access to the OpenClaw-integrated channel or bot, but does not need direct access or credentials for OpenClaw itself. Exploitation depends on the plugin's misconfigured dmPolicy.

What is the safest general fix pattern?

Adopt a fail-closed authorization model: ensure that an empty allowlist results in no authorized users, add explicit checks for empty allowedUserIds, and require at least one valid identifier before the configuration is accepted or activated.
