The version of Google Chrome installed on the remote macOS host is prior to 88.0.4324.182. It is, therefore, affected by multiple vulnerabilities as referenced in the 2021_02_stable-channel-update-for-desktop_16 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
