{"cve":"CVE-2026-105749","nvd":{"published":"2026-10-05T22:16:57.943","modified":"2026-10-08T03:16:35.093","status":"Modified","description":"Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. 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.","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:H","score":6.5},"cwes":["CWE-400","CWE-789"],"references":["https://github.com/docling-project/docling/commit/c5b4429cc6500a344c13edeb22e67610c2159b09","https://github.com/docling-project/docling/pull/4414","https://github.com/docling-project/docling/releases/tag/v2.131.0","https://github.com/docling-project/docling/security/advisories/GHSA-cgc7-9qp3-86m3","https://github.com/docling-project/docling/security/advisories/GHSA-cgc7-9qp3-86m3"],"products":["docling:docling"],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105749","score":0.00291,"percentile":0.21422,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cgc7-9qp3-86m3","url":"https://osv.dev/vulnerability/GHSA-cgc7-9qp3-86m3","summary":"Docling: Unbounded table rowspan/colspan in HTML, JATS, ODS and BoxNote backends causes CPU/memory exhaustion","modified":"2026-10-15T14:55:59.208989812Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.0.0 <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-2026-4195","url":"https://osv.dev/vulnerability/PYSEC-2026-4195","summary":"","modified":"2026-10-15T14:55:59.208989812Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.0.0 <2.131.0"],"fixed":["2.131.0"]}]},{"id":"PYSEC-2026-4211","url":"https://osv.dev/vulnerability/PYSEC-2026-4211","summary":"Docling: Unbounded table rowspan/colspan in HTML, JATS, ODS and BoxNote backends causes CPU/memory exhaustion","modified":"2026-10-15T14:55:59.208989812Z","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).
