## Overview

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 modify internal requests due to improper neutralization of argument delimiters. Special characters in user-supplied input are not handled safely, which could allow additional parameters to be added to a request made by the server.

## Affected

- `api_connect >= 12.1.0.0 <= 12.1.1.2`
- `api_connect >= 10.0.8.0 <= 10.0.8.12`

## Remediation

IBM strongly recommends addressing the vulnerability now by upgrading to v12.1.1.3
