Abstract

IBM WebSphere Application Server is affected by server-side request forgery (CVE-2026-9006)

Download Description

The fix for this APAR is targeted for inclusion in 8.5.5.30 and 9.0.5.29.

For more information, see: Recommended Updates for WebSphere Application Server

Installation Instructions

IMPORTANT

Action is required if and only if the (long-deprecated) AJAX Proxy installable application is deployed. This is believed to be an extremely uncommon configuration.

The AJAX Proxy has two deployment models, the WAR file provided in <WAS_HOME>/installableApps/AjaxProxy.war can be directly installed (deployed) or embedded in your application EAR file.
In either case, the AjaxProxy web module must be updated and re-deployed.  This can be done via the WebSphere Administration Console or via the AdminApp.update task.

More information about the AJAX proxy is available here: https://public.dhe.ibm.com/software/webserver/appserv/library/v85/85528_WAS_web2mobile-ajaxproxy-runtime-help.pdf
