OESA-2026-3788 (CVE-2026-13346)
Vulnerability from osv_openeuler – Published: 2026-09-14 16:34 – Updated: 2026-09-14 16:34 – Source website%changelog * Thu May 14 2026 markeryang <747675909@qq.com> - 23.3.1-11 - Fix CVE-2026-3219
Security Fix(es):
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.(CVE-2026-13346)
