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

Description: The issue is related to an inappropriate implementation in DevTools, which may allow a remote attacker to obtain potentially sensitive information from disk via a crafted HTML page. This is due to a lack of protection for service data.
