{"id":"DEBIAN-CVE-2026-31802","details":"node-tar is a full-featured Tar for Node.js. Prior to version 7.5.11, tar (npm) can be tricked into creating a symlink that points outside the extraction directory by using a drive-relative symlink target such as C:../../../target.txt, which enables file overwrite outside cwd during normal tar.x() extraction. This vulnerability is fixed in 7.5.11.","modified":"2026-09-01T16:06:38.719964204Z","published":"2026-03-10T07:44:58.020Z","upstream":["CVE-2026-31802"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-31802"}],"affected":[{"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+~cs6.1.13-10"}]}],"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+ds1+~cs6.1.13-8","6.2.1+ds1+~cs6.1.13-9","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-2026-31802.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"}]}
