CVE-2026-33340Public exploitNetwork attack vector

Internal-resource access via unvalidated proxy URL

Published Mar 24, 2026 · Updated Mar 24, 2026

SSRF in ParisNeo LoLLMs WebUI 8c5dcef and earlier allows remote attackers to read internal HTTP resources through /api/proxy. The proxy function passes the untrusted request.url value directly to httpx.AsyncClient.get without authentication or destination validation. An unauthenticated network request can reach localhost, internal services, or cloud metadata endpoints and return their response content.
