CVE-2026-7551
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.

OpenHarness is a specialized tool for AI-assisted software engineering research rather than a mainstream development framework or library. Although the vulnerability allows for remote code execution via command injection, its limited adoption in general production environments does not warrant an alert for the broader developer community.
