Insufficient policy enforcement in extensions in Google Chrome prior to 78.0.3904.70 allowed an attacker who convinced a user to install a malicious extension to leak cross-origin data via a crafted Chrome Extension.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
