Description
IBM API Connect versions 12.1.0.0 through 12.1.1.2 contain an authentication vulnerability that could allow a remote attacker to obtain sensitive information and modify API configurations. The flaw arises from insufficient verification of identity information in requests, enabling impersonation of other users.
