What an attacker can do

The source says 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. Vendor/CNA’s CVSS 3.1 assessment (base score 4.9/10) rates confidentiality impact as high; integrity and availability impact as none.
