Description
Langflow versions 1.0.0 through 1.11.1 are susceptible to authenticated remote code execution due to improper enforcement of security restrictions of code generation on the `/api/v1/custom_component` endpoint.
The endpoint accepts attacker controlled code that is then passed to Python's `exec()` function that bypasses security checks enforced by other code paths.
