CVE-2026-42204

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.

Summary		(es) Coolify es una herramienta de código abierto y autoalojable para gestionar servidores, aplicaciones y bases de datos. Desde la 4.0.0-beta.471 hasta la 4.0.0-beta.473, una regresión en SHELL_SAFE_COMMAND_PATTERN permitió ampersands en los campos de comandos personalizados de Docker Compose para compilación, inicio y pre/post-despliegue, lo que permitió a un miembro del equipo autenticado inyectar comandos de shell que se ejecutan en el host. Este problema está solucionado en la versión 4.0.0-beta.474.
