GHSA-hhxq-47xx-j5xx: virtualenv (CVE-2026-113719)

Package	Ecosystem	Affected	Fixed in
virtualenv	PyPI	<21.14.9	21.14.9

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The virtualenv PyPI package, versions before 21.14.9, can delete paths outside the environment when it reseeds an existing environment whose site-packages contains seed-package metadata. An attacker who can influence that metadata, and a local user with deletion rights over the targeted paths, could cause files to be removed when the environment is recreated. The fix is to upgrade to virtualenv 21.14.9, which checks cleanup paths against the environment root; until then, the source advises recreating environments from a trusted empty destination.
