Summary
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 bypass authentication across tenants due to improper authentication. Authentication checks are not sufficiently isolated between tenants, which could allow a user from one tenant to be accepted by another.
