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.\n\n## Affected\n\n- `docling >= 2.91.0, < 2.132.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `docling 2.132.0`\n\n## Package advisory (CVE-2026-105743)\n\nAffected packages:\n\n- `docling >= 2.91.0, < 2.132.0`\n- `docling-slim >= 2.92.0, < 2.132.0`\n\nPatched in:\n\n- `docling 2.132.0`\n- `docling-slim 2.132.0`\n\nSource: https://github.com/advisories/GHSA-pc36-qwjq-x68c\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Lightspeed Core, Red Hat OpenShift AI (RHOAI) · no fix planned: Lightspeed Core, Red Hat OpenShift AI (RHOAI) · updated 2026-10-06 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-105743.json)","depth":"sunlit","depthScore":22,"depthScoreParts":{"impact":22,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
