medium Tenable Self-Hosted Container Security Plugin ID 460309

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-22702)

Solution

Update the virtualenv library and its related packages to version 20.36.1 or later.
