SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identify and mitigate WebSocket security weaknesses that can lead to data leakage, unauthorized access, or service disruption.

Core Features & Use Cases

  • Security-focused WebSocket testing across CSWSH, origin checks, message injection, authentication bypass, and DoS vectors.
  • Structured test scenarios with reproducible payloads and clear remediation guidance.
  • Use case: security teams validate WebSocket endpoints in web apps, APIs, or services to ensure proper origin validation and access controls.

Quick Start

Provide a WebSocket endpoint and allow this skill to initiate a guided security assessment with common WS attack vectors.

Frequently Asked Questions about websocket-security

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

FAQPage Schema
How do I test for Cross-Site WebSocket Hijacking vulnerabilities on my endpoints?▼

Cross-Site WebSocket Hijacking testing is performed by applying crafted payloads to wss endpoints to validate cross-origin configurations and identify origin bypass weaknesses. The skill provides reproducible test scenarios to measure impact safely in controlled environments.

What is the best way to check for WebSocket authentication bypass and message injection flaws?▼

The best way to check for WebSocket authentication bypass and message injection is by applying crafted payloads to endpoints within a safe testing harness. This skill validates access controls and measures the impact of injected messages to ensure proper defenses.

Can I use this to run WebSocket DoS testing against my web application?▼

Yes, you can run WebSocket DoS testing against your web application. The assessment includes DoS scenarios designed to validate defenses and measure service disruption impact, requiring a safe testing harness and controlled targets to ensure non-destructive assessments.

Do I need a controlled testing environment to perform WebSocket security assessments?▼

Yes, a controlled testing environment is required to perform WebSocket security assessments. The skill requires a safe testing harness, controlled targets, and clear success criteria to ensure repeatable, non-destructive assessments across your wss endpoints.

How does this skill identify WebSocket security weaknesses across different endpoints?▼

It identifies WebSocket security weaknesses by applying a variety of crafted payloads to wss endpoints. The skill assesses vulnerabilities including CSWSH, origin bypass, message injection, authentication bypass, and DoS scenarios to validate defenses and measure impact.
