Authenticated intranet access via unvalidated redirects
Published Nov 24, 2025 · Updated Nov 25, 2025
SSRF in QuantumNous New API before 0.9.6 allows remote authenticated users to retrieve intranet resources through a crafted URL. The URL-fetch path applies private-network restrictions only to the initial request, then follows an attacker-controlled HTTP 302 redirect without revalidating its destination. Low-privileged access is required, and successful exploitation makes server-originated requests to otherwise unreachable internal resources.
