Log Injection Vulnerability in IBM WebSphere Application Server

CVE-2026-16189

What is CVE-2026-16189?

IBM WebSphere Application Server versions 9.0 and 8.5 are susceptible to a log injection vulnerability that enables an unauthorized remote attacker to manipulate administrative log entries. This could potentially compromise the integrity of the log data, making it harder for administrators to track legitimate activity and identify malicious actions. By exploiting this weakness, attackers may misrepresent system activities, which could lead to severe security repercussions if not addressed promptly. Administrators are advised to implement the recommended patches from IBM to mitigate this risk.
