Overview

Affected versions of this package are vulnerable to Use After Free via the AppControllerProfileObserver when it handles pre-existing incognito profiles created from the command line in the macOS AppController profile management code. An attacker can trigger heap corruption by serving a crafted HTML page that closes the incognito browser, leaving AppController::lastProfileIfLoaded pointing at freed profile memory.
