CVE-2026-42147
Coolify: SSRF via S3 Storage Endpoint in testConnection()
Description
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.
