Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) via the mutation endpoints exposed on loopback addresses without proper Origin or Referer validation. An attacker can cause unauthorized state changes, such as opening tabs, starting or stopping the browser, or mutating storage and cookies, by enticing a victim to visit a malicious website that triggers cross-origin requests to the local browser control service.

Workaround
This vulnerability can be mitigated by enabling browser control authentication (token/password) and avoiding running with authentication disabled.
