Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products
Version 8.5.0 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• REST API URLs like the following URL can be used to inject an
  unsecure JavaScript statement into REST URL parameter 3:
   https://localhost:9443/rest/wesb/v1/[REST URL parameter 3]
  
  The input that is included in the request is echoed in the
  application's response and this input can be used to inject
  JavaScript into a URL, such as the following  URL:
   http://localhost:9080/rest/wesb/v1/<script>alert(1)</script>
  
  As a result, alert(1) runs.
