NO FIX YET · SEE WHAT TO DO
IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 do not validate user-supplied URLs, so the server can be made to contact internal systems. An attacker with a valid account can learn about services on the internal network.

It checks your repository and tells you if you’re affected, with the fix.
Teams running IBM API Connect in the affected version ranges are exposed, since the server itself makes the outbound requests. The sources do not say which features trigger the URL handling, and an attacker needs an authenticated account. Installations outside the listed ranges are not affected.
