# IBM API Connect: server-side request forgery leaks sensitive information to authenticated users

Link for people: https://infrastack.ai/live/CVE-2026-17406 (this .md is for agents)

IBM API Connect versions 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 fail to block some internal destinations when the server makes requests. A remote attacker with an account can use this to reach blocked addresses and obtain sensitive information.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed API Connect version against the affected ranges `10.0.8.0` to `10.0.8.12` and `12.1.0.0` to `12.1.1.2`
- Review the vendor advisory for the deployment's exact product and fix level: unknown

## Fix

- Move to a release newer than `10.0.8.12` or `12.1.1.2`, per the vendor's fixed versions: exact fixed version unknown from the sources

## From the sources

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 server-side request forgery. Address checks can be bypassed, which could allow the server to reach destinations that should be blocked.
