⚠️ 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:
Ask the user to state the exact target URL, IP, account, or resource.
Ask the user to confirm written authorization and the permitted scope.
Show the exact command(s) and explain their expected effect.
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.

Purpose
Provide a comprehensive, structured reference for the 100 most critical web application vulnerabilities organized by category. This skill enables systematic vulnerability identification, impact assessment, and remediation guidance across the full spectrum of web security threats. Content organized into 15 major vulnerability categories aligned with industry standards and real-world attack patterns.
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
Outputs and Deliverables
Complete vulnerability catalog with definitions, root causes, impacts, and mitigations
Category-based vulnerability groupings for systematic assessment
Quick reference for security testing and remediation
Foundation for vulnerability assessment checklists and security policies
