Official description
IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain sensitive information due to broken object-level authorization. Access checks on keystore objects do not confirm that the requesting user is permitted to read them, which could expose keystore information.
