Coolify: Authenticated RCE via SHELL_SAFE_COMMAND_PATTERN regression → host root

Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. From 4.0.0-beta.471 through 4.0.0-beta.473, a regression in SHELL_SAFE_COMMAND_PATTERN allowed ampersands in custom Docker Compose build, start, and pre/post-deployment command fields, allowing an authenticated team member to inject shell commands that execute on the host. This issue is fixed in version 4.0.0-beta.474.
