    Title
    JoySafeter through 1.0.0 Authenticated RCE via Copilot Standard Mode Shell
    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.
