| Название | ChatGPTNextWeb NextChat 2.16.1 Permissive CORS Wildcard Policy |
|---|
| Описание | NextChat configures its Next.js application to attach maximally permissive CORS response headers to every API endpoint under the /api/* path prefix. The configuration in next.config.mjs (lines 38-63) sets.This configuration allows any website on the internet to make cross-origin requests to all NextChat API endpoints. Because Access-Control-Allow-Headers: * permits custom headers, attacker-controlled JavaScript can set the x-base-url header, which the proxy endpoint (/api/[provider]/[...path]/route.ts) uses to determine the server-side fetch destination. This directly enables cross-origin SSRF attacks. |
