openapi-python-client: Malicious OpenAPI Documents can cause Arbitrary Code Generation
openapi-python-client generates Python clients from OpenAPI documents. Prior to 0.29.1, the generator does not safely neutralize malicious OpenAPI document content before rendering string, docstring, and f-string contexts in generated Python. The generated Python client can contain attacker-controlled Python that executes when a user imports the client, affecting the importing environment's integrity and potentially its confidentiality and availability. This issue is fixed in version 0.29.1.
In openapi-python-client before version 0.5.3, there is a path traversal vulnerability. If a user generated a client using a maliciously crafted OpenAPI document, it is possible for generated files to be placed in arbitrary locations on disk.
In openapi-python-client before version 0.5.3, clients generated with a maliciously crafted OpenAPI Document can generate arbitrary Python code. Subsequent execution of this malicious client is arbitrary code execution.
