Langflow OSS <=1.12.2 - Unauthenticated RCE via Import Code Execution

Langflow OSS 1.0.0 through 1.12.2 is vulnerable to unauthenticated remote code execution via the POST /api/v1/validate/code endpoint, which calls importlib.importmodule on user-supplied import statements, executing module top-level code instead of merely validating syntax. Combined with the defau...
