CVE-2026-105801: Openapi-Generators Openapi-Python-Client

High severity, CVSS 8.4. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Openapi-Generators Openapi-Python-Client: before 0.29.1 (fixed in 0.29.1)
