      "value": "Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 1.19.2, the PUT /api/environments/{id}/templates/variables endpoint, which writes the system-wide .env.global file used for variable substitution in every project's compose file, is missing an admin authorization check. Any authenticated non-admin user can call this endpoint with their bearer token or API key and overwrite the global environment variables that are merged into every project deployment. By overriding values like REGISTRY, IMAGE, DATABASE_URL, or SECRET_KEY that other users reference via ${VAR} in compose files, an attacker can redirect image pulls to attacker-controlled registries (supply-chain RCE on the Docker host), exfiltrate database credentials, or disrupt all projects. This vulnerability is fixed in 1.19.2."

      "value": "Arcane es una interfaz para gestionar contenedores Docker, imágenes, redes y volúmenes. Antes de la versión 1.19.2, el endpoint PUT /api/environments/{id}/templates/variables, que escribe el archivo .env.global de todo el sistema utilizado para la sustitución de variables en el archivo compose de cada proyecto, carece de una comprobación de autorización de administrador. Cualquier usuario autenticado no administrador puede llamar a este endpoint con su token de portador o clave API y sobrescribir las variables de entorno globales que se fusionan en cada despliegue de proyecto. Al sobrescribir valores como REGISTRY, IMAGE, DATABASE_URL o SECRET_KEY que otros usuarios referencian a través de ${VAR} en los archivos compose, un atacante puede redirigir las extracciones de imágenes a registros controlados por el atacante (RCE de cadena de suministro en el host Docker), exfiltrar credenciales de la base de datos o interrumpir todos los proyectos. Esta vulnerabilidad está corregida en la versión 1.19.2."
