Critical

Base vector

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

Name of the Vulnerable Software and Affected Versions: Google Chrome versions prior to 83.0.4103.97

Description: The issue is related to a use after free in WebAuthentication, which can be exploited by a remote attacker who has compromised the renderer process. This could potentially allow the attacker to perform a sandbox escape via a crafted HTML page, impacting the confidentiality, integrity, and availability of protected information.

Recommendations: For versions prior to 83.0.4103.97, update to version 83.0.4103.97 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable WebAuthentication components until the update is applied.
