CVE-2026-22702

18
FAUCET Score

CVE-2026-22702 is a Time-of-Check-Time-of-Use (TOCTOU) vulnerability affecting virtualenv versions prior to 20.36.1, allowing local attackers to perform symlink-based attacks during directory creation. This medium-severity vulnerability (CVSS 4.5) requires local access and high attack complexity, potentially leading to limited impact on confidentiality, integrity, and availability by redirecting virtualenv's app_data and lock file operations. There is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
