Security Bulletin
Summary
API Connect has addressed the following vulnerability.
IBM LoopBack could allow an attacker to bypass authentication if the AccessToken Model is exposed over a REST API, because it is then possible for anyone to create an AccessToken for any User, provided they know the userID and can hence get access to the other users data / access to their privileges (if the user happens to be an Admin for example).
