Q: Which deployments are affected?

IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 are affected.

Q: Does exploitation require authentication?

Yes. The issue is exploitable by a remote authenticated attacker; the provided information does not indicate that unauthenticated access is sufficient.

Q: What access could an attacker gain?

An authenticated user may be able to access sensitive information belonging to other tenants by supplying an insufficiently validated path value in a request.

Updated

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 access sensitive information belonging to other tenants due to improper validation of a path parameter. A path value in a request is not sufficiently validated, which could allow a user to reach data outside their own tenant.
