From 2.13.0 until 2.74.0, the USPTO patent XML parser used the standard xml.sax.parseString() without protection against XML External Entity (XXE) attacks. An attacker could craft malicious USPTO patent XML files with external entity references that could read arbitrary files from the server filesystem, perform Server-Side Request Forgery (SSRF) attacks, or cause denial of service through entity expansion (Billion Laughs attack). The vulnerability affects three USPTO patent format parsers: ICE (v4.x), Grant v2.5, and Application v1.x. This vulnerability is fixed in 2.74.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-776","CWE-611"],"references":["https://github.com/docling-project/docling/security/advisories/GHSA-m88r-rg27-5xfg","https://access.redhat.com/errata/RHSA-2026:60520","https://access.redhat.com/security/cve/CVE-2026-44020","https://bugzilla.redhat.com/show_bug.cgi?id=2492456","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-44020.json"],"products":["docling:docling"],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-44020","score":0.00601,"percentile":0.48446,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-m88r-rg27-5xfg","url":"https://osv.dev/vulnerability/GHSA-m88r-rg27-5xfg","summary":"Docling: Unsafe XML Entity Expansion in USPTO Patent Backend","modified":"2026-08-28T18:45:06.829347750Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.13.0 <2.74.0"],"fixed":["2.74.0"]}]},{"id":"PYSEC-2026-240","url":"https://osv.dev/vulnerability/PYSEC-2026-240","summary":"","modified":"2026-06-27T11:15:05.213146669Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.13.0 <2.74.0"],"fixed":["2.74.0"]}]}],"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).
