Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing neutralization of template directives.

Security engineering principles require use of safe templating APIs and proper escaping of external input.

Input validation rejects or sanitizes untrusted data before it reaches the template engine, stopping injection of special syntax.
