CVE-2026-34152

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, pre-deployment and post-deployment commands are single-quote escaped but then sent through SSH heredoc transport that preserves newlines, allowing an authenticated user to inject additional shell statements that execute on the remote server during deployment. This issue is fixed in version 4.0.0-beta.471.

Summary		(es) Coolify es una herramienta de código abierto y autoalojable para gestionar servidores, aplicaciones y bases de datos. Antes de la versión 4.0.0-beta.471, los comandos de predespliegue y postdespliegue están escapados con comillas simples pero luego se envían a través de un transporte heredoc SSH que preserva los saltos de línea, permitiendo a un usuario autenticado inyectar sentencias de shell adicionales que se ejecutan en el servidor remoto durante el despliegue. Este problema está solucionado en la versión 4.0.0-beta.471.
