Creating Custom Events

What security considerations should be taken into account when using custom events?

function sanitizeEventData(data) {
  // Deep clone to prevent reference manipulation
  const sanitized = JSON.parse(JSON.stringify(data));
  
  // Remove sensitive properties
  delete sanitized.password;
  delete sanitized.token;
  
  return Object.freeze(sanitized);
}

function dispatchSafeEvent(name, data) {
  const event = new CustomEvent(name, {
    detail: sanitizeEventData(data)
  });
  document.dispatchEvent(event);
}

No security needed for events
Only use native events
Implement data sanitization and validation
Security considerations for custom events include: 1. Data sanitization: - Remove sensitive information - Validate input data - Prevent prototype pollution 2. Event scope control: - Limit event bubbling when necessary - Control event dispatch targets - Implement proper authorization 3. Cross-origin considerations: - Handle events from different origins safely - Validate event sources - Implement origin checks 4. Data protection: - Prevent event data manipulation - Secure sensitive information - Implement proper access controls
Disable all events
