api-fuzzing-bug-bounty
Provide comprehensive techniques for testing REST, SOAP, and GraphQL APIs during bug bounty hunting and penetration testing engagements. Covers vulnerability discovery, authentication bypass, IDOR exploitation, and API-specific attack vectors.
⚠️ AUTHORIZED USE ONLY
This skill is for educational purposes or authorized security assessments only.
You must have explicit, written permission from the system owner before using this tool.
Misuse of this tool is illegal and strictly prohibited.
Mandatory confirmation gate
Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
1. Ask the user to state the exact target URL, IP, account, or resource.
2. Ask the user to confirm written authorization and the permitted scope.
3. Show the exact command(s) and explain their expected effect.
4. Wait for explicit confirmation in the current conversation.
Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.
AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.
