CVE-2026-105801
Description
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.
