Description Andrej Nemec 2016-05-12 08:33:28 UTC 
The following flaw was found in Jenkins:

The API URL /computer/(master)/api/xml allowed users with the 'extended read' permission for the master node to see some global Jenkins configuration, including the configuration of the security realm.

This URL now unconditionally sends HTTP 400 Bad Request when accessed. There is no workaround.
