CVE-2026-16435: CWE-650 Trusting HTTP Permission Methods on the Server Side in IBM WebSphere Application Server
IBM WebSphere Application Server 9.0, and 8.5 is affected by an authentication bypass vulnerability when using XD or Intelligent-Management features.
AI Analysis
Technical Summary
CVE-2026-16435 is an authentication bypass vulnerability in IBM WebSphere Application Server 8.5 and 9.0. The issue arises from the server trusting HTTP permission methods improperly when XD or Intelligent-Management features are enabled. This flaw is categorized under CWE-650, which involves trusting HTTP permission methods on the server side, potentially allowing attackers to bypass authentication controls.
Potential Impact
Successful exploitation of this vulnerability could allow an unauthenticated attacker to bypass authentication mechanisms, gaining unauthorized access to the affected WebSphere Application Server. The CVSS v3.1 base score is 5.9 (medium severity), with high confidentiality impact but no impact on integrity or availability. The attack vector is network-based, requiring high attack complexity and no privileges or user interaction.
Mitigation Recommendations
No vendor advisory or patch information is provided in the input data. Patch status is not yet confirmed — check the IBM vendor advisory for current remediation guidance. Until an official fix is available, organizations should consider restricting access to affected features (XD and Intelligent-Management) and monitor for unusual access patterns related to these components.
