PatchTheCVECVE-2026-113724: virtualenv is a tool for creating isolated virtual python environments
CVE-2026-113724 is a medium-severity flaw (CVSS 4.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.9, the safe_delete() deletion error handler responds to a failed removal by reading mode bits with os.lstat(path) and applying owner-write permission with os.chmod(path, ...), which follows a symlink. A planted link inside a read-only directory can therefore cause a victim-owned target outside the destination that is initially not writable by the invoking user
