    The name of the patch is 227500897dfb07fb7d27f7aa570050e62617e3be. It is recommended to apply a patch to
    fix this issue. The identifier VDB-213549 was assigned to this vulnerability. (CVE-2022-3970)

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