From 0.4.7 until 0.24.0, the url argument of partition, partition_html, and partition_md is fetched without host validation in unstructured/partition/auto.py, unstructured/partition/html/partition.py, and unstructured/partition/md.py. An attacker who controls that URL can make a server-side ingestion service request loopback addresses, internal HTTP services, or cloud metadata endpoints through direct targets, redirects, or DNS rebinding. The response body is returned as Element text, allowing internal response disclosure, and side-effecting GET endpoints may also be triggered. This issue is fixed in version 0.24.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:N","score":9.3},"cwes":["CWE-601","CWE-918"],"references":["https://github.com/Unstructured-IO/unstructured/commit/445c95735c4045057f51f399bc04c657751923bd","https://github.com/Unstructured-IO/unstructured/pull/4388","https://github.com/Unstructured-IO/unstructured/releases/tag/0.24.0","https://github.com/Unstructured-IO/unstructured/security/advisories/GHSA-4mvj-m6j5-pmf7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-71428","score":0.00436,"percentile":0.37558,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4mvj-m6j5-pmf7","url":"https://osv.dev/vulnerability/GHSA-4mvj-m6j5-pmf7","summary":"unstructured: Server-Side Request Forgery in the URL-based partitioning","modified":"2026-09-10T12:26:06.471059991Z","packages":[{"ecosystem":"PyPI","name":"unstructured","purl":"pkg:pypi/unstructured","ranges":[">=0.4.7 <0.24.0"],"fixed":["0.24.0"]}]},{"id":"PYSEC-2026-3930","url":"https://osv.dev/vulnerability/PYSEC-2026-3930","summary":"unstructured: Server-Side Request Forgery in the URL-based partitioning","modified":"2026-09-10T12:15:15.056512299Z","packages":[{"ecosystem":"PyPI","name":"unstructured","purl":"pkg:pypi/unstructured","ranges":[">=0.4.7 <0.24.0"],"fixed":["0.24.0"]}]}],"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).
