Jinja2
A widely used template engine in the Python ecosystem. When user input is interpolated into templates and rendered server-side, it can give rise to server-side template injection (SSTI) vulnerabilities.

Chat templates are the rule layer by which inference frameworks convert multi-turn conversations, system prompts, and tool call sequences into model input tokens, usually distributed as Jinja2 templates together with the model weights.
Jinja2 template injection (SSTI) allows attackers to achieve arbitrary code execution (RCE) through injected expressions leveraging the Python object model.
Flask is a lightweight Python web framework based on Werkzeug and Jinja2 that follows the WSGI specification.
For small Python web projects, AI typically recommends Flask or FastAPI as the backend framework, SQLite as the database, and Jinja2 as the templating engine.
