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.","published":"2026-06-26T15:40:42.422Z","modified":"2026-08-07T11:49:54.579440668Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},"epss":{"score":0.00113,"percentile":0.01643,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"docling","fixedVersion":"2.91.0"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/docling-project/docling/releases/tag/v2.91.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44018.json"},{"type":"ADVISORY","url":"https://github.com/docling-project/docling/security/advisories/GHSA-r3xg-rg9j-67fv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44018"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:49:54.579440668Z"}}
