Teams running self-managed IBM API Connect V12 OnPrem, versions v12.1.0.0 through v12.1.1.2. IBM describes a remote attacker and its CVSS vector needs no privileges or user interaction, so a deployment reachable by an attacker over the network is exposed; IBM does not name the endpoint. Teams on other versions (e.g. 10.0.x, not listed in this bulletin entry) or already on v12.1.1.3 can skip it.
