Top 100 Web Vulnerabilities Reference
This skill should be used when the user asks to "identify web application vulnerabilities", "explain common security flaws", "understand vulnerability categories", "learn about injection attacks", "review access control weaknesses", "analyze API security issues", "assess security misconfigurations", "understand client-side vulnerabilities", "examine mobile and IoT security flaws", or "reference the OWASP-aligned vulnerability taxonomy". Use this skill to provide comprehensive vulnerability definitions, root causes, impacts, and mitigation strategies across all major web security categories.
Why this skill is useful
Provides a comprehensive catalog of web vulnerabilities with definitions, impacts, and mitigation strategies that the AI wouldn't reliably generate on its own.

What this skill does
Top 100 Web Vulnerabilities Reference 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 --- Core Workflow Phase 1: Injection Vulnerabilities Assessment Evaluate injection attack vectors targeting data processing components: SQL Injection (1) Definition: Malicious SQL code inserted into input fields to manipulate database queries Root Cause: Lack of input validation, improper use of parameterized queries Impact: Unauthorized data access, data manipulation, database compromise Mitigation: Use parameterized queries/prepared statements, input validation, least privilege database accounts Cross-Site Scripting - XSS (2) Definition: Injection of malicious scripts into web pages viewed by other users Root Cause: Insufficient output encoding, lack of input sanitization Impact: Session hijacking, credential theft, website defacement Mitigation: Output encoding, Content Security Policy (CSP), input sanitization Command Injection (5, 11) Definition: Execution of arbitrary s …
