Overview
@lobehub/chat is a Lobe Chat - an open-source, high-performance chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. Supports one-click free deployment of your private ChatGPT/LLM web application.
Affected versions of this package are vulnerable to Open Redirect via the OIDC redirect handling process. An attacker can cause users to be redirected to arbitrary domains by injecting malicious values into the X-Forwarded-Host or X-Forwarded-Proto headers. This is only exploitable if the deployment's reverse proxy forwards client-supplied X-Forwarded-* headers to the origin as-is, or if the origin trusts these headers without validation.
