SSTImap is the successor to tplmap and the most capable of the template-injection scanners: it detects the engine, escalates to code execution where the engine allows it, and covers Jinja2 among many others.
The lesson from running it against a Django lab is what it cannot do. Django's own template language has no expression evaluation, so every probe comes back clean — a true negative that reads exactly like a missing detection. Add Jinja2 to the same project and the same command reaches remote code execution.
