# IBM API Connect: broken authorization leaks sensitive data to logged-in users

Link for people: https://infrastack.ai/live/CVE-2026-17374 (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 check object-level permissions. A remote attacker with a valid account can read sensitive information belonging to other users or objects.

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

## How to check

- Confirm the installed API Connect version against the affected ranges (10.0.8.0 through 10.0.8.12, 12.1.0.0 through 12.1.1.2)

## Fix

- Move to a release above the affected ranges; the exact fixed version is 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 broken object-level authorization.
