Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, S3 storage endpoint validation only checks URL format and testConnection() sends a server-side request to the configured endpoint, allowing an authenticated user with storage management permissions to make Coolify request internal or metadata-service URLs. This issue is fixed in version 4.0.0-beta.474.

——30Next.js is a React framework for building full-stack web applications. From 13.4.13 to before 15.5.16 and 16.2.5, self-hosted applications using the built-in Node.js server can be vulnerable to server-side request forgery through crafted WebSocket upgrade requests. An attacker can cause the server to proxy requests to arbitrary internal or external destinations, which may expose internal services or cloud metadata endpoints. Vercel-hosted deployments are not affected. This vulnerability is fixed in 15.5.16 and 16.2.5.5dCVE-2023-271597.5 HIG98.3%
