Intranet data disclosure via unchecked proxy URL
Published May 10, 2024 · Updated Aug 2, 2024
Server-side request forgery in LobeHub LobeChat 0.150.5 and earlier allows remote attackers to read intranet data via /api/proxy. The route reads the request body as a URL and passes it directly to server-side fetch without resolving or rejecting private addresses. No login is required, and the endpoint returns the fetched response, exposing services reachable only from the deployment.
