SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires curl, nmap, python3, masscan, subfinder, httpx, nuclei.

What problem does it solve?

This skill addresses the critical security risk of CORS misconfigurations in WordPress REST APIs, which can lead to unauthorized cross-origin data exfiltration and account takeovers.

Core Features & Use Cases

  • Automated Detection: Quickly scan WordPress REST API endpoints for vulnerable CORS headers like Access-Control-Allow-Credentials.
  • Exploit Validation: Generate browser-based Proof of Concept (PoC) code to confirm if sensitive data can be exfiltrated.
  • Use Case: Security researchers can use this to validate findings during bug bounty engagements or pentests, moving from simple detection to demonstrating impact via attack chains.

Quick Start

Use the cors-credential-wordpress skill to scan the target domain example.com for vulnerable REST API endpoints and generate a proof of concept.

Frequently Asked Questions about cors-credential-wordpress

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I scan WordPress REST API endpoints for CORS credential reflection vulnerabilities?

You scan WordPress REST API endpoints for CORS credential reflection vulnerabilities by running this Skill, which automates reconnaissance with curl, masscan, and httpx to detect misconfigured Access-Control-Allow-Credentials headers enabling unauthorized data exfiltration.

What is a WordPress CORS misconfiguration and how does it lead to account takeover?

A WordPress CORS misconfiguration occurs when cross-origin policies reflect arbitrary origins alongside Access-Control-Allow-Credentials, allowing malicious third-party sites to authenticate as the victim and exfiltrate sensitive REST API data for account takeover.

Can I generate a proof of concept for CORS data exfiltration during a pentest?

Yes, you can generate a browser-based proof of concept for CORS data exfiltration during pentests. This Skill validates vulnerable endpoints by creating exploit PoCs that demonstrate potential account takeover vectors.

Do I need to install nuclei and subfinder to audit WordPress cross-origin policies?

Yes, you need nuclei and subfinder installed to comprehensively audit WordPress cross-origin policies. The Skill requires these dependencies alongside curl, nmap, python3, and httpx for complete reconnaissance and exploitation.

What is the best way to detect Access-Control-Allow-Credentials misconfigurations in web applications?

The best way to detect Access-Control-Allow-Credentials misconfigurations in web applications is using automated scanning tools that validate vulnerable REST API endpoints and generate browser-based PoCs to confirm unauthorized cross-origin data exfiltration.
