Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the NotificationsDB module. A remote attacker can trick the victim to visit a specially crafted web page, which passes malicious messages to the parent process where the contents is used to double-index into a JavaScript object. As a result, an attacker can perform prototype pollution and execute arbitrary JavaScript code in the privileged parent process.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
