8.5.5.18, or 9.0.x prior to 9.0.5.5. It is, therefore, affected by a server-side request forgery vulnerability due to
improper input validation by the xlink:href attributes. An unauthenticated, remote attacker can exploit this to cause
the underlying server to make arbitrary GET requests.

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