## Technical details

This vulnerability is a log injection flaw (CWE-117) that stems from improper neutralization of special elements when writing user-controlled data to log files. An unauthenticated, network-based attacker can inject arbitrary data into log messages without authentication or user interaction required. The attack affects the integrity of log files, allowing an attacker to forge log entries, hide malicious activity, or inject false information into audit trails. The vulnerability is fixed in IBM Cloud Pak for Data System version 11.3.1.2-IF1 or later.
