python-virtualenv: virtualenv is a tool for creating isolated virtual python environments
CVE-2026-22702 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-22702, released January 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
virtualenv is a tool for creating isolated virtual python environments. Prior to version 20.36.1, TOCTOU (Time-of-Check-Time-of-Use) vulnerabilities in virtualenv allow local attackers to perform symlink-based attacks on directory creation operations. An attacker with local access can exploit a race condition between directory existence checks and creation to redirect virtualenv's app_data and lock file operations to attacker-controlled locations. This issue has been patched in version 20.36.1.
