A comprehensive guide for penetration testers detailing methods to identify and exploit misconfigurations in OAuth 2.0 and OpenID Connect (OIDC) flows. Techniques cover redirect URI manipulation, authorization code theft, token leakage via headers, and scope escalation during security assessments.

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.

This comprehensive tool assesses critical security flaws in OAuth 2.0 and OpenID Connect (OIDC) implementations. It systematically tests for common vulnerabilities like authorization code interception, redirect URI manipulation, CSRF in OAuth flows, token leakage, and scope escalation. Ideal for penetration testers and security engineers evaluating the robustness of identity providers and client applications.

This skill provides comprehensive functionality for reading, creating, editing, and downloading content from Lark Feishu Docs (Docx/Wiki). Whether accessing via URL or token, it supports structured content manipulation using both XML and Markdown formats (v2 API). Use it for fetching document details, updating specific blocks, and managing embedded media and resources like whiteboards and images. Note that it requires prerequisite knowledge for advanced operations.
