Technical details
A Server-Side Template Injection (SSTI) vulnerability exists in RAGFlow's Agent workflow 'Text Processing' (StringTransform) and 'Message' components. The root cause is the use of Python's unsandboxed 'jinja2.Template' class to render user-supplied strings from the 'Script' and 'Content' fields. An authenticated attacker can bypass the simple '{{' check and use Jinja2 globals (e.g., cycler or namespace) to access the 'os' module and execute arbitrary shell commands. This allows for full remote code execution (RCE) with the privileges of the application process. As of the advisory date, no official patches are available, though migrating to Jinja2's 'SandboxedEnvironment' is the recommended mitigation.
