Teams running IBM API Connect 10.0.8.0 to 10.0.8.12 or V12 OnPrem 12.1.0.0 to 12.1.1.2 where more than one tenant shares the deployment. Any logged-in user could read another tenant's data by supplying identifiers the product does not check against their permissions. IBM's bulletins do not say whether single-tenant installs are affected, so treat them as exposed to any authenticated user until you upgrade. Teams on 10.0.8.13 / 12.1.1.3 or later can skip it.

10.0.8.12, and V12 OnPrem 12.1.0.0 through 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 from other tenants due to improper authorization. Identifiers supplied in requests are not sufficiently checked against the user's permissions, which could allow access to data belonging to other tenants.
