Critical Vulnerability in IBM WebSphere Server
The IBM WebSphere Application Server has been found vulnerable to a significant security flaw, tracked as CVE-2026-15064. This vulnerability poses serious risks, especially for system administrators and hosting providers relying on this platform for their Linux servers.
Summary of the Vulnerability
The vulnerability affects WebSphere Application Server versions 9.0 and 8.5, as well as WebSphere Liberty versions 17.0.0.3 to 26.0.0.7.
