{"id":"DEBIAN-CVE-2026-26960","details":"node-tar is a full-featured Tar for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink inside the extraction directory that points to a file outside the extraction root, enabling arbitrary file read and write as the extracting user. Severity is high because the primitive bypasses path protections and turns archive extraction into a direct filesystem access primitive. This issue has been fixed in version 7.5.8.","modified":"2026-09-01T16:06:36.494088506Z","published":"2026-02-20T02:16:53.883Z","upstream":["CVE-2026-26960"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-26960"}],"affected":[{"package":{"name":"node-tar","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-tar?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.13+~cs7.0.5-1+deb12u1"}]}],"versions":["6.1.13+~cs7.0.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26960.json"}},{"package":{"name":"node-tar","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-tar?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.1+~cs7.0.8-1+deb13u1"}]}],"versions":["6.2.1+~cs7.0.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26960.json"}},{"package":{"name":"node-tar","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-tar?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.2.1+ds1+~cs6.1.13-8"}]}],"versions":["6.2.1+ds1+~cs6.1.13-1","6.2.1+ds1+~cs6.1.13-2","6.2.1+ds1+~cs6.1.13-3","6.2.1+ds1+~cs6.1.13-4","6.2.1+ds1+~cs6.1.13-5","6.2.1+ds1+~cs6.1.13-6","6.2.1+ds1+~cs6.1.13-7","6.2.1+~cs7.0.8-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-26960.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N"}]}
