Name of the Vulnerable Software and Affected Versions: Google Chrome versions prior to 88.0.4324.96

Description: The issue is related to the Page Info component in Google Chrome, where an incorrect security UI allows a remote attacker to conduct spoofing attacks via a crafted HTML page. This can lead to security UI spoofing, potentially deceiving users about the security of a webpage.
