{"id":"BIT-virtualenv-2026-113713","summary":"virtualenv: Temporary app-data can leave dangling seed package links","details":"virtualenv is a tool for creating isolated virtual python environments. From 21.14.8 until 21.14.10, the app-data seeder can leave an environment linked to temporary package files that virtualenv deletes when creation finishes. The environment-variable and configuration-file forms of symlink_app_data can enable this state even though the command-line flag is disabled for temporary app-data. The resulting environment depends on a cache pathname that its owner no longer controls. This issue is fixed in version 21.14.10.","aliases":["CVE-2026-113713","GHSA-4f8h-vr72-p32c"],"modified":"2026-10-29T10:55:30.640343852Z","published":"2026-10-29T09:00:26.656Z","database_specific":{"cpes":["cpe:2.3:a:virtualenv:virtualenv:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/pypa/virtualenv/commit/b81995c3feab9e1edb453c75ffc6616e1a77335e"},{"type":"WEB","url":"https://github.com/pypa/virtualenv/pull/3437"},{"type":"WEB","url":"https://github.com/pypa/virtualenv/releases/tag/21.14.10"},{"type":"WEB","url":"https://github.com/pypa/virtualenv/security/advisories/GHSA-4f8h-vr72-p32c"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-113713"}],"affected":[{"package":{"name":"virtualenv","ecosystem":"Bitnami","purl":"pkg:bitnami/virtualenv"},"ranges":[{"type":"SEMVER","events":[{"introduced":"21.14.8"},{"fixed":"21.14.10"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/virtualenv/BIT-virtualenv-2026-113713.json"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.2"}
