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.\n\n## Affected\n\n- `docling >= 2.45.0, < 2.131.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `docling 2.131.0`\n\n## Package advisory (CVE-2026-105747)\n\nAffected packages:\n\n- `docling >= 2.45.0, < 2.131.0`\n- `docling-slim >= 2.92.0, < 2.131.0`\n\nPatched in:\n\n- `docling 2.131.0`\n- `docling-slim 2.131.0`\n\nSource: https://github.com/advisories/GHSA-3cr3-8m4c-fpxw\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Lightspeed Core, Red Hat OpenShift AI (RHOAI) · no fix planned: Lightspeed Core, Red Hat OpenShift AI (RHOAI) · updated 2026-10-06 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-105747.json)","depth":"sunlit","depthScore":24,"depthScoreParts":{"impact":23.7,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
