Browser functionalities can be widely extended by browser extensions. One of the key features that makes browser extensions so powerful is that they run with "high" privileges. As a consequence, a vulnerable or malicious extension might expose browser, and operating system (OS) resources to possible attacks such as privilege escalation, information stealing, and session hijacking. The resources are referred as browser as well as OS components accessed through browser extension such as accessing information on the web application, executing arbitrary processes, and even access files from a host file system.
