Bug Bounty Tip: SSTI via Payload Fuzzing

Look for:

Reflected input in templates, PDF generators, email renderers, and params like ?name=, ?message=

Test payload: {{7*7}}

If the response shows 49, it may indicate Server-Side Template Injection then escalate with {{7*'7'}} (returns 7777777 in Jinja2) to confirm engine.
