Until a fix is released, restrict access to the /bridge slash command to trusted users only and monitor configurations to limit remote command execution capabilities.
Description
HKUDS OpenHarness has a remote code execution vulnerability in its /bridge slash command. Remote users accepted by configuration can execute arbitrary OS commands by invoking the /bridge spawn command with attacker-controlled input. This allows spawning shell sessions as the OpenHarness process user, risking access to local files, credentials, workspace state, and repository contents.
