## Affected

- coollabsio coolify: fixed in 4.0.0-beta.471

## Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, DatabaseBackupJob interpolates user-controlled database credentials and MongoDB collection exclusion names into backup shell commands without adequate escaping, allowing an authenticated user with database management permissions to execute commands on managed servers. This issue is fixed in version 4.0.0-beta.471.
