What is CVE-2026-7551?

HKUDS OpenHarness possesses a vulnerability in its /bridge command, enabling remote attackers to execute arbitrary operating system commands. By issuing the /bridge spawn command with specially crafted command text, unauthorized users can gain control over the bridge session manager. This allows them to spawn shell sessions as the OpenHarness process user, potentially exposing local files, user credentials, workspace states, and repository contents. Mitigation measures should be implemented to ensure the integrity and confidentiality of the system.
