Medium

Base vector

AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N

Name of the Vulnerable Software and Affected Versions: Google Chrome versions prior to 88.0.4324.146

Description: The issue is related to an inappropriate implementation in Skia, a graphic library used by Google Chrome, which allowed a local attacker to spoof the contents of the Omnibox (URL bar) via a crafted HTML page. This could be exploited by a remote attacker using a specially crafted HTML page, potentially leading to spoofing attacks.

Recommendations: For Google Chrome versions prior to 88.0.4324.146, update to version 88.0.4324.146 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted HTML pages to minimize the risk of exploitation.
