AI-suggested
Upgrade virtualenv to version 21.14.9 or later, where this path traversal and improper deletion issue is fixed. Avoid creating environments that reuse existing package metadata if upgrading is not immediately possible. Creating fresh environments without existing metadata or using the --clear option can also avoid triggering this vulnerability. No other specific mitigations are indicated.
Description
CVE-2026-113719 is a path traversal vulnerability in pypa virtualenv versions prior to 21.14.9. It occurs during environment creation when existing package metadata is reused, allowing deletion of files outside the intended environment directory if the invoking user has sufficient deletion permissions. The issue is fixed in version 21.14.9.
