| Parameter | Position | Path | Description | CWE |
|---|---|---|---|---|
| env.SHELLOPTS | request body | /api/v2/mcp/servers/{name} | Unauthenticated remote code execution via environment variable injection in the MCP stdio launcher. The application fails to block dangerous environment variables like SHELLOPTS, BASHOPTS, and PS4, allowing command substitution in the PS4 variable to execute arbitrary shell commands. | CWE-78 |
| env.BASHOPTS | request body | /api/v2/mcp/servers/{name} | Unauthenticated remote code execution via environment variable injection in the MCP stdio launcher. The application fails to block dangerous environment variables like SHELLOPTS, BASHOPTS, and PS4, allowing command substitution in the PS4 variable to execute arbitrary shell commands. | CWE-78 |
| env.PS4 | request body | /api/v2/mcp/servers/{name} | Unauthenticated remote code execution via environment variable injection in the MCP stdio launcher. The application fails to block dangerous environment variables like SHELLOPTS, BASHOPTS, and PS4, allowing command substitution in the PS4 variable to execute arbitrary shell commands. | CWE-78 |
| action_count | query param | /api/v2/mcp/servers | Endpoint used to trigger the MCP launcher. When combined with a previously registered malicious MCP server via /api/v2/mcp/servers/{name}, this request triggers the execution of the injected shell commands. | CWE-78 |
