CVE-2026-47752

Tugtainer is a self-hosted app for automating updates of Docker containers. Versions prior to 1.30.2 are vulnerable to Server-Side Template Injection (SSTI) in the notification template feature. The `title_template` and `body_template` fields are rendered using an unsandboxed `jinja2.Environment`, allowing any authenticated user to execute arbitrary OS commands as root inside the container. Version 1.30.2 fixes the issue.

Summary		(es) Tugtainer es una aplicación autoalojada para automatizar las actualizaciones de contenedores Docker. Las versiones anteriores a la 1.30.2 son vulnerables a la Inyección de Plantillas del Lado del Servidor (SSTI) en la característica de plantilla de notificación. Los campos ’title_template’ y ’body_template’ se renderizan usando un ’jinja2.Environment’ sin sandbox, permitiendo a cualquier usuario autenticado ejecutar comandos arbitrarios del sistema operativo como root dentro del contenedor. La versión 1.30.2 corrige el problema.
