From 2.0.0 until 2.131.0, the HTML, JATS, OpenDocument spreadsheet, and BoxNote backends, including docling/backend/html_backend.py, docling/backend/jats_backend.py, and docling/backend/boxnote_backend.py, accept the rowspan and colspan attribute values without an upper bound and execute loops or allocate a table grid proportional to the declared span. A very small document can therefore cause sustained CPU use or multi-gigabyte memory allocation, and the document_timeout setting does not interrupt the single backend conversion call. Export through the TableData.grid property can further materialize the oversized grid. This issue is fixed in 2.131.0.","state":0,"publishedAt":"2026-10-05T21:36:53.431+00:00","modifiedAt":"2026-10-08T02:29:09.184+00:00","affected":[{"ecosystem":"Vendor product","name":"docling","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"docling-project\",\n                    \"product\": \"docling\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 2.131.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"docling-slim","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"docling-project\",\n                    \"product\": \"docling-slim\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.92.0, < 2.131.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/docling-project/docling/security/advisories/GHSA-cgc7-9qp3-86m3","https://github.com/docling-project/docling/pull/4414","https://github.com/docling-project/docling/commit/c5b4429cc6500a344c13edeb22e67610c2159b09","https://github.com/docling-project/docling/releases/tag/v2.131.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105749","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105749","identifiers":["CVE-2026-105749"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
