Vulnerability Details

pip would incorrectly handle doubly-encoded package URLs from indexes allowing for files to be installed to arbitrary locations on disk even when installing wheels.
This vulnerability requires downloading or installing a package from a malicious package index to succeed, malicious packages alone are not able to exploit this vulnerability. Note that this vulnerability only materially impacts users running "pip download" with the "--only-binary" option as installing source distributions from an untrusted index is already an unsafe operation that executes code during install time.
