## Technical details

A server-side request forgery (SSRF) vulnerability exists in IBM WebSphere Application Server Liberty versions 17.0.0.3 through 26.0.0.7. The flaw is located within the apiDiscovery-1.0 feature, which is used to discover and document REST APIs. A remote authenticated attacker with low privileges can exploit this vulnerability by sending a specially crafted request, causing the server to perform unauthorized network requests. This can be used to scan internal networks, access metadata services, or pivot to other internal systems that are not directly accessible from the internet. IBM has released interim fix PH71873 and recommends upgrading to Liberty Fix Pack 26.0.0.8 or later.
