CVE-2026-10852: CWE-476 NULL Pointer Dereference in IBM WebSphere Application Server
IBM WebSphere Application Server and IBM WebSphere Application Server Liberty are vulnerable to denial of service in the WebSphere WebServer Plug-in component when an attacker can pass crafted requests to the web server.
AI Analysis
Technical Summary
CVE-2026-10852 is a medium severity denial of service vulnerability in IBM WebSphere Application Server and Liberty editions. It arises from a NULL pointer dereference in the WebSphere WebServer Plug-in component. An unauthenticated attacker can cause the server to crash or become unresponsive by sending crafted requests to the web server. The vulnerability affects versions 8.5 and 9.0. There is no vendor advisory or patch currently available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation results in denial of service (DoS) by crashing or disrupting the WebSphere Application Server's web server plug-in component. This causes service unavailability but does not impact confidentiality or integrity of data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting access to the affected web server plug-in component from untrusted networks to reduce exposure.
