Prior to 21.14.9, download_wheel() writes package-index downloads directly into the reusable wheel/house cache before selecting a verification target from pip's textual Saved output. With default-index digest comparison enabled, a controlled package index can inject a misleading Saved line through a discarded link's data-requires-python attribute; this forged-line variant also requires knowledge of an absolute path to the genuine bundled wheel. The wrong path can then be hashed, while a digest mismatch leaves the rejected archive in the cache for later selection without verification. A separate rejected-cache-file variant requires control over downloaded data or archive selection but not the forged-line prerequisites. Explicit custom-index exceptions are outside the promised PyPI comparison, and the issue does not independently bypass TLS or establish control of default PyPI. This issue is fixed in version 21.14.9.","state":0,"publishedAt":"2026-10-20T19:09:45.096+00:00","modifiedAt":"2026-10-20T19:19:51.08+00:00","affected":[{"ecosystem":"Vendor product","name":"virtualenv","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pypa\",\n                    \"product\": \"virtualenv\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 21.14.9\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/pypa/virtualenv/security/advisories/GHSA-494p-63j8-28p3","https://github.com/pypa/virtualenv/pull/3430","https://github.com/pypa/virtualenv/commit/7babec66e043e1cc8bc66869a063653898719d96","https://github.com/pypa/virtualenv/releases/tag/21.14.9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113714","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113714","identifiers":["CVE-2026-113714"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
