Summary

JoySafeter through 1.0.0 contains a remote code execution vulnerability that allows authenticated users to run operating system commands via an unsandboxed execute tool in Copilot standard mode. Attackers can self-register, select standard mode in the WebSocket chat.start extension, and have the agent invoke subprocess.run with shell=True on the host to access other tenants' data and server secrets.

Risk Assessment

Access to other tenants' data and server secrets is possible, potentially leading to confidentiality breaches and system compromise.

Recommendation

Update JoySafeter to a version later than 1.0.0; until then, disable Copilot standard mode or restrict self-registration and OS command execution.
