Skill UI

This skill focuses on identifying and exploiting type juggling vulnerabilities in PHP web applications. It demonstrates techniques such as loose comparison bypass (==), type coercion using JSON/serialized input, and leveraging magic hash collisions to circumvent authentication mechanisms, password verification, and general application logic checks in a controlled security testing environment.

This guide details how to implement robust API schema validation using OpenAPI Specification (OAS) and JSON Schema. It enforces strict input/output contracts, preventing critical vulnerabilities such as injection attacks (SQLi, XSS), data leakage, and mass assignment by validating data types and structure at the API gateway or development level.

This guide details how to implement multi-layered API threat protection using Google Apigee. It covers critical security policies including JSON/XML content validation, OAuth 2.0 enforcement, SpikeArrest rate limiting, and advanced regex patterns to defend against OWASP Top 10 threats. Ideal for establishing robust API security controls and meeting compliance requirements.

This skill provides comprehensive knowledge on using JSON Web Tokens (JWT) for secure authentication and authorization. It covers implementing various cryptographic signing algorithms (such as HS256, RS256, ES256, and EdDSA), validating signatures, enforcing claim constraints (like expiration time), and implementing robust defenses against common JWT vulnerabilities, including algorithm confusion and the 'none' algorithm attack. Ideal for building secure, scalable web APIs.

Automate comprehensive vulnerability management by deploying and operating Greenbone/OpenVAS. This skill guides the use of the python-gvm library to programmatically manage the entire scanning lifecycle: creating scan targets, executing complex vulnerability scans via the Greenbone Management Protocol (GMP), monitoring progress, and parsing detailed XML reports into actionable JSON findings. Ideal for security assessments and compliance checks.

This skill details advanced methodologies for bypassing Content Security Policy (CSP) protections. It covers exploiting misconfigurations, such as using 'unsafe-inline' or 'unsafe-eval', leveraging JSONP endpoints, manipulating base-uri, and leaking nonces. It is essential for web application penetration testing and security auditing when standard XSS payloads are blocked by CSP.

This tool automates the process of executing the JWT none algorithm attack. It demonstrates how to bypass signature verification by setting the 'alg' header to 'none' in a JSON Web Token. This vulnerability allows attackers to forge tokens with arbitrary claims, such as escalating privileges or impersonating other users, and is crucial for penetration testing and API security auditing.

Kubesec is a powerful open-source tool designed to perform comprehensive security risk analysis on Kubernetes resource manifests (YAML/JSON). It automatically detects critical misconfigurations, potential privilege escalation vectors, and deviations from industry security best practices. It provides actionable scoring and hardening recommendations, making it essential for CI/CD pipelines, security auditing, and automated compliance checks.

This guide details a comprehensive methodology for testing JSON Web Token (JWT) implementations against critical security vulnerabilities. It covers attacks such as algorithm confusion (e.g., RS256 to HS256), 'None' algorithm bypass, Key ID (kid) injection, JKU/X5U manipulation, and brute-forcing weak secrets. Essential for API and SSO security assessments.

Provides CLI-driven access control for a Discord channel by reading/writing the shared JSON state. Use it to approve pairings, edit allowlists, set DM/group policies, and keep the channel server informed without touching Discord directly.

Helps developers answer codebase questions by leveraging the `.understand-anything/knowledge-graph.json` graph; walks through project metadata, nodes, edges, and layers to explain dependencies and contexts.

`jq` is the standard and powerful CLI tool for querying, filtering, and reshaping JSON data. This skill provides expert-level practical patterns for working with deeply nested structures, handling complex transformations (like flattening, renaming, and grouping), and integrating JSON logic into shell pipelines. Essential for parsing API outputs (AWS, GitHub), log files, and building robust Bash scripts.
