Lookout Analysis
The most likely way for an attacker to exploit this vulnerability would be to send a link leading to a malcrafted webpage to their target in hopes that the target still has a vulnerable version of Chrome on their device. A successful exploit may grant a threat actor access to Chrome's capabilities without needing to root the device. Mobile device management (MDM) tools will not detect a successful exploitation. In the event of a successful exploit, the actor could have access to any capability that the browser has.
