Key insight
The vulnerability requires active social engineering manipulation via a crafted HTML page and affects only users who click on malicious links, therefore posing low risk for well-trained users.
Description
An authorization check in the ControlledFrame component of Google Chrome prior to version 153.0.8010.36 is insufficiently implemented. This allows an attacker to bypass system access restrictions through a crafted HTML page and social engineering. The vulnerability has a medium security severity and requires active user interaction (clicking a malicious link). No evidence of active exploitation has been reported so far.
