CVE-2026-14529 is a critical server-side request forgery vulnerability affecting IBM WebSphere Application Server traditional 8.5 and 9.0, and IBM WebSphere Application Server Liberty versions 17.0.0.3 through 26.0.0.8, when the SIP container feature sipServlet-1.1 is enabled. The flaw is remotely exploitable over the network with low attack complexity, requires no privileges, and does not require user interaction. The issue allows attacker-controlled requests to be issued by the vulnerable server, indicating insufficient protection of a critical request-handling function in the SIP container path. IBM mapped the issue to CWE-306.
