Prior to 1.5.1, the URLInputHandler class in docling_graph/core/input/handlers.py makes HTTP requests to user-supplied URLs without validating whether the target resolves to a private, loopback, or link-local IP address. The URLValidator only checks for a valid scheme and non-empty netloc, performing no IP-level validation. Additionally, requests.head() was called with allow_redirects=True, allowing an attacker to redirect requests to internal endpoints via an intermediary URL. An attacker who can control the --source CLI argument or PipelineConfig.source API parameter can trigger Server-Side Request Forgery (SSRF). This vulnerability is fixed in 1.5.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N","score":5.7},"cwes":["CWE-601","CWE-918"],"references":["https://github.com/docling-project/docling-graph/security/advisories/GHSA-fqph-j6v6-jvgx"],"products":[],"source":"nvd","synced_at":"2026-10-26T14:27:29.784594657+00:00"},"epss":{"cve":"CVE-2026-44520","score":0.00188,"percentile":0.083,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fqph-j6v6-jvgx","url":"https://osv.dev/vulnerability/GHSA-fqph-j6v6-jvgx","summary":"docling-graph has SSRF via Missing Internal IP Validation in URLInputHandler","modified":"2026-07-13T16:43:11.508373487Z","packages":[{"ecosystem":"PyPI","name":"docling-graph","purl":"pkg:pypi/docling-graph","ranges":["<1.5.1"],"fixed":["1.5.1"]}]},{"id":"PYSEC-2026-2458","url":"https://osv.dev/vulnerability/PYSEC-2026-2458","summary":"docling-graph has SSRF via Missing Internal IP Validation in URLInputHandler","modified":"2026-07-13T16:31:40.072921364Z","packages":[{"ecosystem":"PyPI","name":"docling-graph","purl":"pkg:pypi/docling-graph","ranges":["<1.5.1"],"fixed":["1.5.1"]}]}],"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).
