{"id":"DEBIAN-CVE-2026-13346","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.","modified":"2026-09-01T16:06:27.832836310Z","published":"2026-07-29T19:16:44.267Z","upstream":["CVE-2026-13346"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-13346"}],"affected":[{"package":{"name":"python-pip","ecosystem":"Debian:12","purl":"pkg:deb/debian/python-pip?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["23.0.1+dfsg-1","23.1.2+dfsg-1","23.1.2+dfsg-2","23.2+dfsg-1","23.2.1+dfsg-1","23.3+dfsg-1","24.0+dfsg-1","24.0+dfsg-2","24.1+dfsg-1","24.1.1+dfsg-1","24.2+dfsg-1","24.3.1+dfsg-1","25.0+dfsg-1","25.0.1+dfsg-1","25.1+dfsg-1","25.1.1+dfsg-1","25.2+dfsg-1","25.3+dfsg-1","26.0+dfsg-1","26.0.1+dfsg-1","26.1.1+dfsg-1","26.1.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13346.json"}},{"package":{"name":"python-pip","ecosystem":"Debian:13","purl":"pkg:deb/debian/python-pip?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.1.1+dfsg-1","25.2+dfsg-1","25.3+dfsg-1","26.0+dfsg-1","26.0.1+dfsg-1","26.1.1+dfsg-1","26.1.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13346.json"}},{"package":{"name":"python-pip","ecosystem":"Debian:14","purl":"pkg:deb/debian/python-pip?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.1.1+dfsg-1","25.2+dfsg-1","25.3+dfsg-1","26.0+dfsg-1","26.0.1+dfsg-1","26.1.1+dfsg-1","26.1.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13346.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
