There is a MEDIUM severity vulnerability affecting pip.
pip would treat console_scripts and gui_scripts as paths instead of file names
without sanitizing the resolved absolute path to the installation directory,
leading to entry points being installed outside the installation directory.
Please see the linked CVE ID for the latest information on affected versions:
