CVE-2026-47752 Details
Description
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.
A Server-Side Template Injection (SSTI) vulnerability has been identified in Tugtainer versions prior to 1.30.2.

This flaw allows any authenticated user to execute arbitrary operating system commands as root within the container.
