Summary

agentscope-ai AgentScope versions 2.0.0 through 2.0.11 are affected. In the MCP Workspace API, the subprocess.Popen call in src/agentscope/mcp/_config.py does not properly neutralize special elements in the command argument, which is an OS command injection flaw (CWE-78). A remote attacker can inject OS commands, and a public exploit is referenced.
