DescriptionCVE.org

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, the file upload endpoint (app/Http/Controllers/UploadController.php) for database backup restore uploads did not enforce file type or size validation, allowing an authenticated user to upload unexpected or oversized files that could affect service availability. This issue is fixed in version 4.0.0-beta.474.
