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 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.

This skill provides a comprehensive framework for security auditing LLM agents that possess external tools (file system access, command execution, network calls). It employs advanced dialogue probing techniques—such as command injection, path traversal, and SSRF attempts—to identify vulnerabilities where the agent might be induced to execute unexpected or malicious code, or access sensitive resources. Essential for red teaming and securing agent functionalities.

A comprehensive playbook detailing how web applications can be vulnerable to attacks by manipulating the HTTP Host header. Covers critical techniques such as password reset poisoning, Web Cache Poisoning, Server-Side Request Forgery (SSRF), and Virtual Host bypass. Essential reading for penetration testers and security researchers.

HTTP Parameter Pollution (HPP) occurs when a single request contains multiple instances of the same parameter key. Different components in the request path (e.g., WAFs, proxies, application frameworks) may parse these duplicate keys using different rules (first value, last value, array join). This skill teaches how to exploit these discrepancies to bypass security checks, execute SSRF, or manipulate business logic.

This router serves as the main entry point for comprehensive injection testing. It helps security professionals classify dangerous input flows—such as XSS, SQLi, SSRF, XXE, etc.—by determining the final sink or interpreter (e.g., browser context, database, XML parser, shell). Use it when unsure which specific injection vector to prioritize.

A comprehensive playbook detailing how open redirect vulnerabilities can be exploited. Covers finding redirect parameters, advanced filter bypass techniques (e.g., protocol-relative, userinfo), and complex exploitation chains including OAuth token theft, SSRF, and Tabnabbing.

This comprehensive playbook details expert techniques for exploiting Server-Side Request Forgery (SSRF). It covers bypassing URL filters, accessing cloud metadata endpoints (AWS, GCP, Azure), utilizing advanced protocols like Gopher, and chaining vulnerabilities to achieve Remote Code Execution (RCE) in real-world scenarios. Ideal for penetration testers and security researchers.

A comprehensive playbook for testing XSLT injection vulnerabilities. This guide details advanced attack chains, starting with processor fingerprinting (Java, PHP, .NET, libxslt). It covers critical vectors including XXE (External Entities), Server-Side Request Forgery (SSRF) via document(), arbitrary file writing (EXSLT), and achieving Remote Code Execution (RCE) through language-specific extensions.

A comprehensive, expert-level playbook covering XML External Entity (XXE) vulnerabilities. This guide details advanced attack techniques across multiple contexts, including SOAP, REST, SVG, and Office files. Key topics covered include blind detection, out-of-band (OOB) data exfiltration, local file reading (e.g., /etc/passwd), and chaining XXE to achieve SSRF or RCE.

This skill audits Model Context Protocol (MCP) servers to detect critical AI security vulnerabilities. It scans for tool poisoning, tool shadowing, rug pulls, SSRF, and unauthenticated exposure. Use it before integrating new tools or during security reviews to ensure agent reliability and prevent supply chain attacks.

A guide for security researchers focused on finding exploitable, remote-reachable vulnerabilities for bug bounties or responsible disclosure. It emphasizes high-signal flaws such as SSRF, RCE, and SQL injection, while guiding users through the professional triage and PoC creation process for penetration testing.
