Security Vulnerabilities
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 improper validation of external references. When schemas are validated, references to external resources are not sufficiently restricted, which could allow the server to retrieve content it should not access.

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 perform unauthorized actions and obtain sensitive information due to missing authorization. Certain operations do not verify that the user is permitted to act on the targeted resource, which could allow other users' API keys to be deleted.

IBM API Connect 12.1.0.0 through 12.1.1.2 could allow a remote attacker to gain unauthorized access to sensitive API catalog and runtime configuration data due to improper authentication. Information supplied by the client is not sufficiently verified, which could allow a caller to appear as a trusted party.

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 improper authorization. Authorization checks are not applied when certain organization URLs are resolved, which could allow access to information belonging to others.

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 path parameter injection. Values in the request path are not sufficiently validated, which could allow access to data belonging to other tenants.
