Description Adam Mariš 2018-05-10 04:47:06 EDT

The built-in Jenkins user database optionally allows user registration. This feature did not properly sanitize user names, allowing registration of user names containing control characters.

This could be used to confuse administrators (appearing to be a different user) while preventing deletion of such users through the UI.
