DOM-based XSS: The Hidden Threat

Unlike reflected or stored XSS, DOM-based XSS occurs entirely in the browser. The malicious payload never reaches the server, making it harder to detect with traditional WAFs.

Common sources include location.hash, document.referrer, and postMessage.

DOM XSS is underrated. Most scanners miss it completely.

We use textContent instead of innerHTML now. Problem solved!
