Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.466, the sentinel_token setting is used in shell commands without sufficient validation, allowing an authenticated user with access to server Sentinel settings to inject shell syntax and execute commands on the host when Sentinel is restarted.
