Finding a bug is only half the job. Vague reports get bounced. Clear reporting speeds triage, improves severity decisions, and builds long-term reputation.

What You Will Learn

• Write titles that survive triage queues

• Produce stranger-proof reproduction steps

• Justify severity without hype

• Recommend practical mitigations

Report Structure

2. Standalone summary

3. Severity with rationale

4. Exact reproduction steps

5. Minimal redacted PoC evidence

6. Impact scenarios

7. Remediation suggestions

8. Self-validation before submit
