Google Chrome’s V8 engine, before 157.0.8103.78, fails to enforce authorization and lets a remote attacker bypass the web origin policy. The attacker needs the victim to open a crafted HTML page. Successful use can cross origin boundaries that the browser should keep separate. Users of Chrome builds older than that release are affected.
What to do: Update Google Chrome to 157.0.8103.78 or later.
