Research direction
Start by reviewing Bandit's existing plugin architecture and security checks, then examine how Flask's render_template_string can introduce server-side template injection. Define the unsafe-use cases and add coverage showing that they are detected without flagging safe usage; the issue does not name specific files or tests.
