"The remote host contains a Spring Framework version that is prior to 5.2.20 or 5.3.x prior to 5.3.17. It is, therefore,

routing expression that may result in denial of service condition.

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