CVE-2018-1778 is a vulnerability of currently unknown severity. IBM LoopBack (IBM API Connect 2018.1, 2018.4.1, 5.0.8.0, and 5.0.8.4) could allow an attacker to bypass authentication if the AccessToken Model is exposed over a REST API, 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 userÃ¢ÂÂs data / access to their privileges (if the user happens to be an Admin for example). IBM X-Force ID: 148801.. EPSS estimates a 3.45% chance of exploitation in the next 30 days.
