How to fix?

Upgrade Minimos:latest py3-supported-pip to version 26.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-supported-pip package and not the py3-supported-pip package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
