{"cve":"CVE-2026-105747","nvd":{"published":"2026-10-05T22:16:57.633","modified":"2026-10-07T18:54:39.350","status":"Analyzed","description":"Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.45.0 until 2.131.0, METS-GBS format detection in docling/datamodel/document.py and the backend in docling/backend/mets_gbs_backend.py call tarfile.TarFile.getmembers() before enforcing the max_member_count limit, causing the full archive member list to be allocated before the limit can stop processing. A small gzip-compressed tar archive with a very large number of empty members can therefore consume memory proportional to the declared member count, including during format detection before the allowed_formats restriction is applied. This issue is a residual weakness in the member-count protection added for CVE-2026-44018. This issue is fixed in 2.131.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-409","CWE-770"],"references":["https://github.com/docling-project/docling/commit/ebae65cd71c37c88b36185b406a449b92d8f7ffa","https://github.com/docling-project/docling/pull/4412","https://github.com/docling-project/docling/releases/tag/v2.131.0","https://github.com/docling-project/docling/security/advisories/GHSA-3cr3-8m4c-fpxw"],"products":["docling:docling"],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105747","score":0.00299,"percentile":0.22371,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-3cr3-8m4c-fpxw","url":"https://osv.dev/vulnerability/GHSA-3cr3-8m4c-fpxw","summary":"Docling: METS-GBS archive member limit enforced after full member enumeration (memory exhaustion during format detection)","modified":"2026-10-15T14:56:00.401934996Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.45.0 <2.131.0"],"fixed":["2.131.0"]},{"ecosystem":"PyPI","name":"docling-slim","purl":"pkg:pypi/docling-slim","ranges":[">=2.92.0 <2.131.0"],"fixed":["2.131.0"]}]},{"id":"PYSEC-2026-4194","url":"https://osv.dev/vulnerability/PYSEC-2026-4194","summary":"","modified":"2026-10-15T14:56:00.401934996Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.45.0 <2.131.0"],"fixed":["2.131.0"]}]},{"id":"PYSEC-2026-4209","url":"https://osv.dev/vulnerability/PYSEC-2026-4209","summary":"Docling: METS-GBS archive member limit enforced after full member enumeration (memory exhaustion during format detection)","modified":"2026-10-15T14:56:00.401934996Z","packages":[{"ecosystem":"PyPI","name":"docling-slim","purl":"pkg:pypi/docling-slim","ranges":[">=2.92.0 <2.131.0"],"fixed":["2.131.0"]}]}],"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).
