CVE-2026-102925 3 Pypa, Python, Virtualenv 3 Virtualenv, Virtualenv, Virtualenv 2026-11-09 7.8 High
virtualenv is a tool for creating isolated virtual python environments. Prior to 21.7.13, the generated activate (bash and zsh) and activate.fish scripts place values already escaped by shlex.quote inside an additional quoted context. In the bash and zsh script, a crafted virtual environment path reaches __VIRTUAL_ENV__ when a relocated environment's recorded directory is absent; in the fish script, crafted Tcl or Tk library paths reach __TCL_LIBRARY__ or __TK_LIBRARY__. The surplus quotes can terminate the data-only quoted run and leave shell metacharacters parsed as commands when a user sources the activation script, allowing code execution with that user's privileges. This issue is fixed in version 21.7.13.
CVE-2026-22702 1 Virtualenv 1 Virtualenv 2026-04-18 4.5 Medium
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-2024-53899 2 Redhat, Virtualenv 8 Enterprise Linux, Openshift Devspaces, Rhel Aus and 5 more 2025-02-10 8.4 High
virtualenv before 20.26.6 allows command injection through the activation scripts for a virtual environment. Magic template strings are not quoted correctly when replacing. NOTE: this is not the same as CVE-2024-9287.
CVE-2013-5123 5 Debian, Fedoraproject, Pypa and 2 more 6 Debian Linux, Fedora, Pip and 3 more 2024-11-21 5.9 Medium
The mirroring support (-M, --use-mirrors) in Python Pip before 1.5 uses insecure DNS querying and authenticity checks which allows attackers to perform man-in-the-middle attacks.
