SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the critical security risks associated with real-time bidirectional communication, specifically identifying vulnerabilities like Cross-Site WebSocket Hijacking (CSWSH), insecure authentication, and improper channel authorization.

Core Features & Use Cases

Origin Validation Testing: Detects if the server fails to validate the Origin header, which could allow unauthorized third-party websites to hijack user sessions.
Injection Surface Identification: Probes for SQL, NoSQL, Command, and Template injection surfaces within WebSocket message fields.
Use Case: A security researcher can use this skill to audit a real-time chat application to ensure that users cannot subscribe to private channels belonging to other users or tenants.

Quick Start

Use the websocket-security skill to audit the target endpoint wss://api.example.com/v1/realtime for origin validation and channel authorization flaws.

FAQPage Schema

How do I test WebSocket endpoints for Cross-Site WebSocket Hijacking vulnerabilities?▼

Testing WebSocket origin validation involves checking if the server rejects unauthorized Origin headers. This skill probes the target endpoint to detect missing origin verification, which leaves real-time communication channels vulnerable to session hijacking by malicious third-party sites.

What is the best way to check WebSocket authentication and channel authorization controls?▼

The best way to check WebSocket authentication is to probe the target endpoint for enforcement gaps. This skill validates authentication mechanisms and channel-level authorization to identify tenant isolation failures where users might access private channels belonging to others.

How do I identify injection surfaces within WebSocket message fields?▼

Identifying WebSocket injection surfaces requires probing message fields with malicious payloads. This skill tests real-time communication inputs for SQL, NoSQL, Command, and Template injection vulnerabilities to uncover insecure data handling within the bidirectional message stream.

Can I use this for penetration testing real-time chat applications without disrupting system stability?▼

Yes, you can use this for penetration testing real-time chat applications safely. The skill requires authorized target scope and strictly adheres to non-destructive probing policies, ensuring system stability is maintained while auditing WebSocket security controls.

When do I need to audit WebSocket security controls for tenant isolation failures?▼

You need to audit WebSocket security controls for tenant isolation failures when securing multi-tenant real-time applications. This skill ensures users cannot subscribe to private channels belonging to other tenants by validating channel-level authorization across the communication protocol.
