Summary

Tugtainer before version 1.30.2 is 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.

Risk Assessment

An attacker can fully compromise the Docker container, leading to a breach of confidentiality, integrity, and availability of data and potentially the entire system.

Recommendation

Immediately update Tugtainer to version 1.30.2 or later.
