# IBM API Connect: broken object-level authorization exposes sensitive information to users

Link for people: https://infrastack.ai/live/CVE-2026-17387 (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 they should not see.

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

## How to check

- Check the installed IBM 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

## Fix

- Move to a fixed version: unknown, the sources do not state it

## Timeline

## 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.
