Vulnerability Overview

PDF.js is vulnerable to Arbitrary JavaScript Execution in versions prior to 4.2.67. This is due to a missing type check when handling fonts. This makes it possible for authenticated attackers, with contributor-level or above permissions, to execute arbitrary JavaScript if they can successfully trick a user into opening a crafted PDF file.
