Technical details
The planner agent in ExecutionAction.run extracts and executes Python code from model responses using unsandboxed exec() with full globals and builtins. An attacker sends a request to the unauthenticated POST /solve endpoint with crafted inputs that cause the planner LLM to emit malicious Python in an interpreter action block. The code is extracted from markdown fences and executed server-side without any sandbox, AST allowlist, or authentication gate, providing full code execution as the server process user (typically root in Docker).
