What an attacker can do

An attacker can craft an invite so that a single tap on the legitimate-looking "Connect to my Home Assistant server" button opens their /auth/authorize endpoint in the URL-less onboarding WebView, presenting a look-alike login page that captures the victim's credentials. Vendor/CNA’s CVSS 3.1 assessment (base score 4.3/10) rates confidentiality impact as low; integrity and availability impact as none.
