Inappropriate implementation in permissions in Google Chrome prior to 85.0.4183.83 allowed a remote attacker to spoof the contents of a permission dialog via a crafted HTML page.
Weakness
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
