> **⚠️ 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.
# Top 100 Web Vulnerabilities Reference
## Detailed Guide
Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.
## Prerequisites
- Basic understanding of web application architecture (client-server model, HTTP protocol)
- Familiarity with common web technologies (HTML, JavaScript, SQL, XML, APIs)
- Understanding of authentication and authorization concepts
- Access to web application security testing tools (Burp Suite, OWASP ZAP)
- Knowledge of secure coding principles recommended
## Constraints and Limitations
- Vulnerability definitions represent common patterns; specific implementations vary
- Mitigations must be adapted to technology stack and architecture
- New vulnerabilities emerge continuously; reference should be updated
- Some vulnerabilities overlap across categories (e.g., IDOR appears in multiple contexts)
- Effectiveness of mitigations depends on proper implementation
- Automated scanners cannot detect all vulnerability types (especially business logic)
