{"cve":"CVE-2026-105743","nvd":{"published":"2026-10-05T22:16:57.030","modified":"2026-10-08T03:16:34.960","status":"Analyzed","description":"Docling simplifies document processing by parsing diverse formats and providing integrations with the generative AI ecosystem. From 2.91.0 until 2.132.0, validate_url_safety in docling/backend/utils/image_resource_loader.py validates a hostname with a single IPv4 lookup and then allows the HTTP client to resolve and parse the original URL again, permitting DNS rebinding, mixed public and internal address records, and backslash authority parser disagreement to reach internal services. HTMLBackendOptions(render_page=True) also allows HTTP and HTTPS browser requests without validating their resolved destination. Exploitation requires remote fetching to be enabled, and response content is exposed only when it is decoded as an image or passively rendered in a page screenshot. This issue is fixed in 2.132.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-367","CWE-918"],"references":["https://github.com/docling-project/docling/commit/5e469137f275ffc443306a30d12a3a45bceb80fb","https://github.com/docling-project/docling/pull/4420","https://github.com/docling-project/docling/releases/tag/v2.132.0","https://github.com/docling-project/docling/security/advisories/GHSA-pc36-qwjq-x68c"],"products":["docling:docling"],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-105743","score":0.00201,"percentile":0.09906,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-pc36-qwjq-x68c","url":"https://osv.dev/vulnerability/GHSA-pc36-qwjq-x68c","summary":"Docling has SSRF guard bypass in remote resource fetching (DNS rebinding / multi-record resolution; no IP validation in HTML render mode)","modified":"2026-10-15T14:56:05.258865953Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.91.0 <2.132.0"],"fixed":["2.132.0"]},{"ecosystem":"PyPI","name":"docling-slim","purl":"pkg:pypi/docling-slim","ranges":[">=2.92.0 <2.132.0"],"fixed":["2.132.0"]}]},{"id":"PYSEC-2026-4190","url":"https://osv.dev/vulnerability/PYSEC-2026-4190","summary":"","modified":"2026-10-15T14:56:05.258865953Z","packages":[{"ecosystem":"PyPI","name":"docling","purl":"pkg:pypi/docling","ranges":[">=2.91.0 <2.132.0"],"fixed":["2.132.0"]}]},{"id":"PYSEC-2026-4214","url":"https://osv.dev/vulnerability/PYSEC-2026-4214","summary":"Docling has SSRF guard bypass in remote resource fetching (DNS rebinding / multi-record resolution; no IP validation in HTML render mode)","modified":"2026-10-15T14:56:05.258865953Z","packages":[{"ecosystem":"PyPI","name":"docling-slim","purl":"pkg:pypi/docling-slim","ranges":[">=2.92.0 <2.132.0"],"fixed":["2.132.0"]}]}],"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).
