{"cve":"CVE-2026-32711","nvd":{"published":"2026-03-20T02:16:33.600","modified":"2026-06-17T10:36:15.123","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-22"],"references":["https://github.com/pydicom/pydicom/commit/6414f01a053dff925578799f5a7208d2ae585e82","https://github.com/pydicom/pydicom/releases/tag/v3.0.2","https://github.com/pydicom/pydicom/security/advisories/GHSA-v856-2rf8-9f28"],"products":["pydicom:pydicom"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32711","score":0.00289,"percentile":0.21553,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-v856-2rf8-9f28","url":"https://osv.dev/vulnerability/GHSA-v856-2rf8-9f28","summary":"pydicom has a path traversal in FileSet/DICOMDIR ReferencedFileID allows file access outside the File-set root","modified":"2026-07-13T07:26:29.581553611Z","packages":[{"ecosystem":"PyPI","name":"pydicom","purl":"pkg:pypi/pydicom","ranges":[">=3.0.0 <3.0.2"],"fixed":["3.0.2"]},{"ecosystem":"PyPI","name":"pydicom","purl":"pkg:pypi/pydicom","ranges":["<2.4.5"],"fixed":["2.4.5"]}]},{"id":"PYSEC-2026-2266","url":"https://osv.dev/vulnerability/PYSEC-2026-2266","summary":"","modified":"2026-07-13T07:15:41.176781370Z","packages":[{"ecosystem":"PyPI","name":"pydicom","purl":"pkg:pypi/pydicom","ranges":[">=2.0.0 <3.0.2"],"fixed":["3.0.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
