CVE-2026-14529Network attack vector

Unauthenticated SSRF via enabled SIP container

Published Jul 29, 2026 · Updated Jul 29, 2026

SSRF in IBM WebSphere Application Server 8.5 and 9.0 and Liberty 17.0.0.3 through 26.0.0.8 allows remote attackers to access internal resources. The SIP container accepts an unauthenticated request that triggers a server-side request, but IBM has not disclosed the controlling field or destination parsing. Exposure requires sipServlet-1.1 to be enabled and permits access to resources reachable from the application server.
