{"id":"PYSEC-2026-2144","details":"Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.45.0 until 2.91.0, the METS-GBS backend's XML parsing and the input document format detection lacked security controls. An attacker could craft malicious METS-GBS archives that, when processed, could read sensitive files, exhaust system resources, or cause application crashes. This vulnerability is fixed in 2.91.0.","aliases":["CVE-2026-44018","GHSA-r3xg-rg9j-67fv"],"modified":"2026-07-13T07:15:23.386028754Z","published":"2026-06-26T16:16:30.767Z","references":[{"type":"ADVISORY","url":"https://github.com/docling-project/docling/releases/tag/v2.91.0"},{"type":"FIX","url":"https://github.com/docling-project/docling/security/advisories/GHSA-r3xg-rg9j-67fv"}],"affected":[{"package":{"name":"docling","ecosystem":"PyPI","purl":"pkg:pypi/docling"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.45.0"},{"fixed":"2.91.0"}]}],"versions":["2.45.0","2.46.0","2.47.0","2.47.1","2.48.0","2.49.0","2.50.0","2.51.0","2.52.0","2.53.0","2.54.0","2.55.0","2.55.1","2.56.0","2.56.1","2.57.0","2.58.0","2.59.0","2.60.0","2.60.1","2.61.0","2.61.1","2.61.2","2.62.0","2.63.0","2.64.0","2.64.1","2.65.0","2.66.0","2.67.0","2.68.0","2.69.0","2.69.1","2.70.0","2.71.0","2.72.0","2.73.0","2.73.1","2.74.0","2.75.0","2.76.0","2.77.0","2.78.0","2.79.0","2.80.0","2.81.0","2.82.0","2.83.0","2.84.0","2.85.0","2.86.0","2.87.0","2.88.0","2.89.0","2.90.0"],"ecosystem_specific":{},"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/docling/PYSEC-2026-2144.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
