# IBM App Connect Enterprise: remote attacker can inject arbitrary HTML into pages

Link for people: https://infrastack.ai/live/CVE-2026-18196 (this .md is for agents)

IBM App Connect Enterprise versions 13.0.1.0 through 13.0.8.2 and 12.0.1.0 through 12.0.12.30 fail to neutralize output, so a remote attacker can inject arbitrary HTML. The sources do not describe the exact impact beyond HTML injection.

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

## How to check

- Check the installed IBM App Connect Enterprise version against the affected ranges (13.0.1.0 through 13.0.8.2, 12.0.1.0 through 12.0.12.30)

## From the sources

IBM App Connect Enterprise 13.0.1.0 through 13.0.8.2, and 12.0.1.0 through 12.0.12.30 could allow a remote attacker to inject arbitrary HTML due to improper output neutralization.
