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.

A comprehensive checklist detailing advanced attack methodologies for JSON Web Tokens (JWT). Covers critical misconfigurations such as algorithm confusion (alg:none, RS256→HS256), weak secret brute forcing, header injection (kid, jku, jwk), cache poisoning, and improper validation. Also provides specific vectors for extracting JWTs from mobile environments (Android/iOS). Ideal for penetration testers conducting deep security assessments on authentication systems.

This comprehensive checklist guides thorough security testing of OAuth 2.0 and OpenID Connect (OIDC) protocols. It covers advanced vulnerabilities such as authorization code interception, PKCE bypass, CSRF flaws, and improper scope validation. The methodology emphasizes modern industry standards like FAPI (DPoP, JAR, PAR), making it essential for penetration testers and security researchers assessing web application integrity and API security.

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.

This skill provides a comprehensive operational checklist for identifying and exploiting HTTP Parameter Pollution (HPP) vulnerabilities. It details how various web technologies (ASP.NET, PHP, Python, etc.) handle duplicate parameters differently (e.g., first-wins, last-wins, concatenation). Use this skill during penetration testing to discover flaws in parameter parsing, which can lead to bypassing WAFs, performing logic manipulation, or achieving unauthorized access.

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.

This skill provides a comprehensive checklist and detailed methodology for detecting HTTP Request Smuggling vulnerabilities. It covers various desynchronization types (CL.TE, TE.CL, TE.TE), including HTTP/2 and modern variants. Use this when penetration testing multi-server architectures, proxies, or load balancers to identify potential security bypasses, unauthorized access, or cache poisoning risks.

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.

This skill provides a comprehensive checklist and methodology for identifying Server-Side Template Injection (SSTI) vulnerabilities. It covers template engine identification (e.g., Jinja2, Twig), polyglot payload generation, systematic detection methods, and executing engine-specific Remote Code Execution (RCE) payloads. Ideal for security professionals testing web application input sanitization.
