GHSA-mj59-h3q9-ghfh: OpenClaw: MCP stdio server env could load dangerous startup variables from workspace config

Workspace MCP stdio configuration could pass dangerous process-startup environment variables such as NODE_OPTIONS, LD_PRELOAD, or BASH_ENV to the spawned MCP server process. In a malicious workspace, this could make the MCP child load attacker-controlled code when the operator starts a session that uses that MCP server.

The impact is limited to local/workspace trust boundaries and requires the operator to run OpenClaw in a workspace containing the malicious MCP configuration. Severity is therefore medium, not high/critical.
