Technical Analysis

CVE-2026-16184 is an authentication bypass vulnerability affecting IBM WebSphere Application Server versions 9.0 and 8.5. A remote attacker can exploit this flaw by sending a specially crafted unauthenticated request to bypass authentication mechanisms. The vulnerability is classified under CWE-862 (Missing Authorization). The CVSS 3.1 vector indicates network attack vector, high attack complexity, no privileges required, no user interaction, unchanged scope, low confidentiality and integrity impact, and high availability impact.

Potential Impact

Successful exploitation allows an unauthenticated remote attacker to bypass authentication controls, potentially gaining unauthorized access to the application server. This could compromise system availability and lead to limited confidentiality and integrity impacts as indicated by the CVSS vector.
