CVE-2026-27955

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the executeInDocker() helper wraps commands in bash -c '{$command}' without escaping single quotes. User-controlled docker_compose_custom_build_command and docker_compose_custom_start_command fields are interpolated directly, allowing a single quote to break out of the bash -c argument and execute commands on the managed server host (outside the intended Docker container context). This vulnerability is fixed in 4.0.0-beta.464.

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.464, el asistente executeInDocker() envuelve los comandos en bash -c ’{$command}’ sin escapar las comillas simples. Los campos controlados por el usuario docker_compose_custom_build_command y docker_compose_custom_start_command se interpolan directamente, permitiendo que una comilla simple escape del argumento bash -c y ejecute comandos en el host del servidor gestionado (fuera del contexto del contenedor Docker previsto). Esta vulnerabilidad está corregida en la versión 4.0.0-beta.464.
