Description
CVE-2026-17303 is a server-side request forgery (SSRF) vulnerability in IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2. It allows a remote authenticated attacker to cause the server to make requests to internal network resources by supplying a crafted URL that is not properly validated. This improper validation can lead to unauthorized access to internal systems.
