A comprehensive checklist and methodology for penetration testing file upload endpoints. Covers critical vulnerabilities such as MIME type bypass, extension bypass, magic byte manipulation, path traversal, and stored XSS. Essential for web application security assessment and bug bounty hunting, guiding testers through basic testing to advanced exploitation techniques like Null Byte injection and double extensions.

A comprehensive checklist designed for assessing the security posture of GraphQL endpoints. It covers advanced vulnerabilities such as introspection abuse, IDOR, query depth/complexity DoS, injection attacks (SQLi/NoSQLi), and authorization bypass mechanisms. Essential for professional penetration testing and bug bounty hunting.

This comprehensive checklist guides penetration testers through discovering Insecure Direct Object References (IDOR). It covers techniques like object ID enumeration, horizontal and vertical privilege escalation, and parameter manipulation. Use it for web application pentests and bug bounty hunting to identify broken access control vulnerabilities.

This comprehensive checklist guides users through identifying and exploiting open redirect vulnerabilities in web applications. It covers parameter identification, advanced bypass techniques (e.g., URL encoding, CRLF injection), and chaining the vulnerability with other flaws like OAuth or SSRF. Ideal for web application penetration testing and bug bounty hunting.

A comprehensive methodology and checklist for identifying and exploiting race conditions (TOCTOU) in web applications. It guides users to find timing windows, detect vulnerabilities like double-spend or rate limit bypass, and exploit concurrent request flaws in state-changing business logic. Essential for penetration testing and bug bounty hunting.

This skill provides a comprehensive, structured methodology and checklist for identifying Remote Code Execution (RCE) vulnerabilities across various web applications. It covers advanced attack vectors such as OS command injection, Server-Side Template Injection (SSTI), insecure deserialization, file upload flaws, and XXE. Use this guide during web application penetration testing or bug bounty hunting to systematically discover arbitrary code execution paths.

A comprehensive guide to advanced SQL injection (SQLi) methodologies for offensive security assessments and bug bounty hunting. Covers all major injection types, including error-based, boolean/time-based blind, out-of-band, and second-order injection. Provides specific payloads and techniques for MySQL, MSSQL, PostgreSQL, Oracle, and NoSQL databases, along with methods for bypassing WAFs, exploiting GraphQL, WebSocket, and modern API filters. Includes full automation workflows using tools like sqlmap.

This comprehensive guide provides a detailed methodology for detecting and exploiting Server-Side Request Forgery (SSRF) vulnerabilities. It covers basic, blind, and out-of-band techniques, including testing against cloud metadata endpoints (AWS/GCP/Azure) and advanced bypass methods like DNS rebinding. It is an essential resource for web application security testing and bug bounty hunting.

A comprehensive checklist and methodology for testing Cross-Site Scripting (XSS) vulnerabilities. Covers all major types, including Stored, Reflected, DOM, and Blind XSS, along with advanced techniques like CSP bypass, polyglot payloads, and event handler injection. Essential for web application security testing and bug bounty hunting to identify and mitigate malicious script injection risks.

This comprehensive checklist details how to test for XML External Entity (XXE) injection vulnerabilities. It covers classic, blind, error-based, and out-of-band techniques, enabling testers to identify weaknesses in XML parsers. The methodology includes finding various injection points (e.g., file uploads, SOAP/REST endpoints) and exploiting potential risks like file disclosure, SSRF, and DoS. Use this guide for robust web application security testing and bug bounty hunting.

Squirrel is an advanced, full-cycle AI coding skill designed to guide software development from concept to production. It automatically detects the current project state (greenfield, in-progress, or mature) and adapts an 8-phase engineering pipeline. This comprehensive workflow covers planning, building, rigorous testing, bug hunting, code polishing, documentation, and deployment readiness, ensuring high-quality, maintainable results.

A comprehensive, top-level routing skill for authorized web security assessment, bug bounty hunting, and API penetration testing. It guides the agent through a structured methodology, covering the entire attack lifecycle from reconnaissance and vulnerability triage (XSS, SQLi, IDOR, etc.) to advanced business logic flaw identification. Use this skill to ensure thorough, systematic security analysis.
