Apache Tomcat through versions 7.0.88, 8.0.52, 8.5.31 and 9.0.8 have defaults settings for the CORS filter that are insecure and enable 'supportsCredentials' for all origins.

Comment 22 Doran Moppert 2019-07-15 04:11:16 UTC 
Mitigation:

When using the CORS filter, it is recommended to configure it explicitly for your environment.  In particular, the combination of `cors.allowed.origins = *` and `cors.support.credentials = True` should be avoided as this  can leave your application vulnerable to cross-site scripting (XSS). For details on configuring CORS filter, please refer to https://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#CORS_Filter
