CVE-2026-85673

LLaMA-Factory SSRF Guard Bypass via Redirect and DNS Rebinding

Published Sep 4, 2026 CVSS 4.0 · 8.7 High EPSS < 1% KEV · Not listed
Description
LLaMA-Factory contains a server-side request forgery vulnerability in the OpenAI-compatible API multimodal media URL handler that allows unauthenticated attackers to bypass SSRF validation. The check_ssrf_url guard validates URLs once but requests.get follows redirects and re-resolves DNS without re-validation, enabling attackers to use HTTP redirects or DNS rebinding to access internal addresses and cloud metadata endpoints.
