CVE-2026-14525: CWE-306 Missing Authentication for Critical Function in IBM WebSphere Application Server - Liberty
IBM WebSphere Application Server - Liberty versions 17.0.0.3 through 26.0.0.8 are vulnerable to an authentication bypass when the rtcomm-1.0 or rtcommGateway-1.0 feature is enabled. This vulnerability allows unauthenticated attackers to access critical functions without proper authentication.
AI Analysis
Technical Summary
CVE-2026-14525 is a critical vulnerability in IBM WebSphere Application Server - Liberty affecting versions 17.0.0.3 through 26.0.0.8. The issue is a missing authentication for critical functions (CWE-306) when the rtcomm-1.0 or rtcommGateway-1.0 feature is enabled, enabling an attacker to bypass authentication controls. The CVSS v3.1 base score is 9.4, indicating high impact on confidentiality, integrity, and low impact on availability. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.
Potential Impact
An attacker can bypass authentication mechanisms to access critical functions in the affected IBM WebSphere Application Server - Liberty installations when the vulnerable features are enabled. This can lead to full compromise of confidentiality and integrity of the system, with limited impact on availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to disable the rtcomm-1.0 and rtcommGateway-1.0 features if they are not required, or apply any vendor-recommended temporary mitigations once published.
