# IBM API Connect: broken authorization lets logged-in users read sensitive data

Link for people: https://infrastack.ai/live/CVE-2026-17391 (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 authorization. A remote attacker with a valid account can obtain sensitive information belonging to other objects.

_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 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2
- Review the IBM security bulletin for API Connect for the affected component list (unknown from the sources)

## Fix

- Move to a release newer than the affected ranges (exact fixed version unknown from the sources)

## Timeline
