Description
The vulnerability allows a remote attacker to compromise the affected system.
The issue exists due to the way pip handles software versioning during installation with --extra-index-url option enabled, which results in the version with the highest version number to be installed, even if the user had intended to obtain a private package from a private index. A remote attacker compromise the repository and force installation of a malicious package.
Remediation
Install updates from vendor's website.
