CVE-2026-34597

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.470, a critical Authenticated Host Remote Code Execution (RCE) vulnerability was discovered in Coolify. The flaw resides in the handling of user-defined build parameters for the Nixpacks build pack. Specifically, the install_command provided by a user is directly concatenated into a shell command string that is executed on the deployment host during the building phase. An attacker can leverage this to escape the intended build context and execute arbitrary commands with host-level privileges. This vulnerability is fixed in 4.0.0-beta.470.

Summary		(es) Coolify es una herramienta de código abierto y autoalojable para gestionar servidores, aplicaciones y bases de datos. Antes de 4.0.0-beta.470, una crítica vulnerabilidad de ejecución remota de código (RCE) autenticada en el host fue descubierta en Coolify. La falla reside en el manejo de los parámetros de construcción definidos por el usuario para el paquete de construcción Nixpacks. Específicamente, el install_command proporcionado por un usuario se concatena directamente en una cadena de comando de shell que se ejecuta en el host de despliegue durante la fase de construcción. Un atacante puede aprovechar esto para escapar del contexto de construcción previsto y ejecutar comandos arbitrarios con privilegios a nivel de host. Esta vulnerabilidad está corregida en 4.0.0-beta.470.
