Prior to 21.14.9, the stdlib venv creator reads generated pyvenv.cfg with str.splitlines() and merges parsed keys over virtualenv's selected configuration. An untrusted caller who influences the destination pathname can include a line-boundary character such as U+2028 to inject keys including home and include-system-site-packages, causing path data to change configuration structure before final output. Setting include-system-site-packages to true weakens environment isolation, while an altered home can change which standard-library files the interpreter loads if the attacker also controls that location. The builtin creator does not use this readback path. This issue is fixed in version 21.14.9.","state":0,"publishedAt":"2026-10-20T19:42:55.011+00:00","modifiedAt":"2026-10-23T02:01:48.925+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:L/AC:H/AT:P/PR:N/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":2,"severity":"LOW"}],"references":["https://github.com/pypa/virtualenv/security/advisories/GHSA-qmx5-4p3x-wvqf","https://github.com/pypa/virtualenv/pull/3426","https://github.com/pypa/virtualenv/commit/b0008a58885ded9227faf8f910c6c402712c750a","https://github.com/pypa/virtualenv/releases/tag/21.14.9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-113715","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-113715","identifiers":["CVE-2026-113715"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
