# IBM API Connect: authentication bypass exposes gateway configuration to remote attackers

Link for people: https://infrastack.ai/live/CVE-2026-17313 (this .md is for agents)

IBM API Connect versions 12.1.0.0 through 12.1.1.2 contain an authentication bypass through an alternate path. A remote attacker can obtain sensitive information and take control of gateway configuration.

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

## Affected

- vendor:API Connect V12 OnPrem affected >= 12.1.0.0, <= 12.1.1.2 fixed 12.1.1.3

## How to check

Check your IBM API Connect V12 OnPrem version. v12.1.0.0 through v12.1.1.2 is affected; v12.1.1.3 contains the fix. Also check whether any API Connect gateway or management endpoint can be reached from untrusted networks. IBM's bulletin does not say which path is used or whether a setting is required.

## Fix

Upgrade IBM API Connect V12 OnPrem to v12.1.1.3 (Fix Central: https://www.ibm.com/support/pages/node/7290205). IBM lists no workarounds or mitigations.
