CVE-2026-60731Network attack vector

Authenticated takeover via missing RMI authentication

Published Aug 18, 2026 · Updated Aug 19, 2026

Authentication bypass in Oracle WebCenter Portal Composer 12.2.1.4.0 and 14.1.2.0.0 allows remote authenticated users to take over the server via RMI. Oracle and NVD identify the Composer RMI surface and a CWE-306 mapping, but no public advisory or patch detail names the specific endpoint or shows how authentication is skipped. Reachability requires network access to the RMI service and valid low-privilege credentials; successful exploitation can fully compromise the portal with confidentiality, integrity, and availability impact.
