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.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:H/VA:N/SC:H/SI:H/SA:H","score":8.4},"cvss_v3":null,"cwes":["CWE-94","CWE-116","CWE-150"],"references":["https://github.com/openapi-generators/openapi-python-client/commit/1c99af478892e5bbe6583b92acba431c9dec9186","https://github.com/openapi-generators/openapi-python-client/pull/1483","https://github.com/openapi-generators/openapi-python-client/releases/tag/v0.29.1","https://github.com/openapi-generators/openapi-python-client/security/advisories/GHSA-5293-mq8x-g3xj"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105801","score":0.00139,"percentile":0.03204,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-5293-mq8x-g3xj","url":"https://osv.dev/vulnerability/GHSA-5293-mq8x-g3xj","summary":"openapi-python-client: Malicious OpenAPI Documents can cause Arbitrary Code Generation","modified":"2026-10-15T14:55:35.768688332Z","packages":[{"ecosystem":"PyPI","name":"openapi-python-client","purl":"pkg:pypi/openapi-python-client","ranges":["<0.29.1"],"fixed":["0.29.1"]}]},{"id":"PYSEC-2026-4245","url":"https://osv.dev/vulnerability/PYSEC-2026-4245","summary":"openapi-python-client: Malicious OpenAPI Documents can cause Arbitrary Code Generation","modified":"2026-10-15T14:45:12.938675050Z","packages":[{"ecosystem":"PyPI","name":"openapi-python-client","purl":"pkg:pypi/openapi-python-client","ranges":["<0.29.1"],"fixed":["0.29.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
