CVE-2026-13346  (opens in a new tab)

How to fix?

Upgrade SLES:15.5 python39-base to version 3.9.25-150300.4.109.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python39-base package and not the python39-base package as distributed by SLES. See How to fix? for SLES:15.5 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.
