CVE-2026-14981: CWE-400 Uncontrolled Resource Consumption in IBM WebSphere Application Server
IBM WebSphere Application Server versions 8.5 and 9.0 are affected by a denial of service vulnerability due to uncontrolled resource consumption in the HTTP channel. This vulnerability arises from unbounded allocation of resources without limits, potentially allowing an attacker to exhaust server resources. The CVSS v3.1 base score is 7.5, indicating a high severity impact on availability. No official patch or remediation guidance is currently provided by IBM. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-14981 is a denial of service vulnerability in IBM WebSphere Application Server 8.5 and 9.0 caused by uncontrolled resource consumption (CWE-400) in the HTTP channel. The flaw allows unbounded allocation of resources without limits, which can lead to resource exhaustion and service disruption. The vulnerability has a CVSS 3.1 score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability. No vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation can cause denial of service by exhausting server resources, impacting availability of IBM WebSphere Application Server 8.5 and 9.0. There is no impact on confidentiality or integrity reported. No known active exploitation has been observed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider limiting exposure of the HTTP channel to untrusted networks and monitor for unusual resource consumption patterns.
