HKUDS OpenHarness contains a remote code execution vulnerability in the /bridge slash command that allows remote senders accepted by configuration to execute arbitrary operating system commands. Attackers can invoke the /bridge spawn command with attacker-controlled command text that is forwarded to the bridge session manager and executed through the shared shell subprocess helper, allowing them to spawn shell sessions as the OpenHarness process user and access local files, credentials, workspace state, and repository contents.
AnalysisAI
Remote code execution in HKUDS OpenHarness allows authenticated remote attackers to execute arbitrary operating system commands via the /bridge slash command. Attackers with remote sender privileges can invoke '/bridge spawn' with malicious command arguments that bypass input validation and execute directly through the shell subprocess helper, granting access to local files, credentials, workspace state, and repository contents. …

RemediationAI
Within 24 hours: Identify all HKUDS OpenHarness instances and document which have remote sender privileges enabled and are accessible to untrusted users. Within 7 days: Apply vendor patch (commit 438e373) to all instances; verify /bridge command restrictions are enforced for remote invocations via post-patch testing. …
