| Titel | disler aider-mcp-server 0.1.0 Command Injection |
|---|
| Beschreibung | aider-mcp-server exposes an MCP tool named aider_ai_code that accepts attacker-controlled relative_editable_files. After Aider finishes, the server concatenates those file names into a shell command string and executes:
diff_cmd = f"git -C {working_dir} diff -- {files_arg}"
subprocess.check_output(diff_cmd, shell=True, text=True, stderr=subprocess.PIPE)
Because files_arg is built with " ".join(relative_editable_files) and there is no quoting or escaping, a caller can inject shell metacharacters such as ;, #, `, or $(). An untrusted MCP client can therefore execute arbitrary operating-system commands on the host running the server. |
