Positive Technologies (AI Summary)

CVSS v2.0

7.1

High

Base vector

AV:N/AC:M/Au:N/C:C/I:N/A:N

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

Description The issue is related to insufficient validation of untrusted input in the clipboard, which can be exploited by a local attacker to bypass site isolation. This can potentially allow a remote attacker to access confidential data due to a lack of standard permission mechanisms.

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 access to clipboard contents to minimize the risk of exploitation.
