CVE-2026-22702 (GCVE-0-2026-22702)

Vulnerability from cvelistv5 – Published: 2026-01-10 06:05 – Updated: 2026-01-12 16:44
VLAI?
Title
virtualenv Has TOCTOU Vulnerabilities in Directory Creation
Summary
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.
Severity ?
