{"id":"DEBIAN-CVE-2026-32711","details":"pydicom is a pure Python package for working with DICOM files. Versions 2.0.0-rc.1 through 3.0.1 are vulnerable to Path Traversal through a maliciously crafted DICOMDIR ReferencedFileID when it is set to a path outside the File-set root. pydicom resolves the path only to confirm that it exists, but does not verify that the resolved path remains under the File-set root. Subsequent public FileSet operations such as copy(), write(), and remove()+write(use_existing=True) use that unchecked path in file I/O operations. This allows arbitrary file read/copy and, in some flows, move/delete outside the File-set root. This issue has been fixed in version 3.0.2.","modified":"2026-09-14T17:03:27.440126643Z","published":"2026-03-20T02:16:33.600Z","upstream":["CVE-2026-32711"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-32711"}],"affected":[{"package":{"name":"pydicom","ecosystem":"Debian:12","purl":"pkg:deb/debian/pydicom?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.1-1","2.4.3-1","2.4.3-2","2.4.3-3","3.0.2-1","3.0.2-2","3.0.2-3","3.0.2-4","3.0.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32711.json"}},{"package":{"name":"pydicom","ecosystem":"Debian:13","purl":"pkg:deb/debian/pydicom?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.3-2","2.4.3-3","3.0.2-1","3.0.2-2","3.0.2-3","3.0.2-4","3.0.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32711.json"}},{"package":{"name":"pydicom","ecosystem":"Debian:14","purl":"pkg:deb/debian/pydicom?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.2-1"}]}],"versions":["2.4.3-2","2.4.3-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32711.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:H"}]}
