Name of the Vulnerable Software and Affected Versions Google Chrome versions prior to 81.0.4044.92

Description The issue is related to insufficient policy enforcement in extensions, allowing an attacker to obtain potentially sensitive information from process memory via a crafted Chrome Extension. This can happen if a user is convinced to install a malicious extension. The attacker, acting remotely, can exploit this to gain access to confidential data.

Recommendations For versions prior to 81.0.4044.92, update to version 81.0.4044.92 or later to resolve the issue. As a temporary workaround, consider restricting the installation of extensions to only trusted sources until the update is applied.
