Summary
IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 are vulnerable to server-side request forgery. A remote authenticated attacker could obtain sensitive information.
Risk Assessment
The ability to force server-side requests risks access to internal resources and data leakage, affecting the confidentiality of the API environment.
Recommendation
Update IBM API Connect to a version containing the fix. Implement outbound request filtering and monitor for suspicious traffic.
