WebSocket Exploitation Generator

WebSocket exploitation targets the persistent full-duplex ws:// or wss:// channel that browsers open after an HTTP upgrade handshake. Because messages skip the normal request flow, they often miss CSRF protection, input validation, and authorization checks, exposing the connection to hijacking, injection, and message tampering that the WebSocket generator helps you test.

CSWSH happens when the handshake relies only on cookies and ignores the Origin header, so an attacker page can open an authenticated socket. The WebSocket generator emits an HTML PoC that connects to the target from a foreign origin and exfiltrates received messages, plus the curl and wscat commands to confirm the server accepts a forged Origin.

Once the channel is open, server-side message handling is often weaker than the HTTP layer: the WebSocket generator builds payloads that inject SQLi, XSS, or command sequences into JSON messages, tamper with a userId or role field for authorization bypass, and abuse handshake or proxy quirks for smuggling, since many gateways only inspect the initial upgrade and not subsequent frames.

Yes. The WebSocket Exploitation generator is free and runs 100% in your browser, so the endpoints, tokens, and messages you configure are never sent to a server. Use the generated PoCs only against WebSocket services you are authorized to assess, such as in-scope bug bounty or penetration-testing targets.
