The version of Google Chrome installed on the remote macOS host is prior to 89.0.4389.114. It is, therefore, affected by multiple vulnerabilities as referenced in the 2021_03_stable-channel-update-for-desktop_30 advisory. Note that Nessus has not tested for this issue but has instead relied only on the applicationβs self-reported version number.
