"The version of TeamViewer Client installed on the remote MacOS host is prior to 15.52. It is, therefore, affected
by an insecure symlink following vulnerability. A local attacker with unprivileged access could potentially elevate
privileges or conduct a denial-of-service attack by overwriting the symlink.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
