CVE-2026-60672Network attack vector

Server takeover via missing T3 IIOP authentication

Published Aug 18, 2026 · Updated Aug 20, 2026

Authentication bypass in the Core component of Oracle WebLogic Server allows remote attackers to take over the server via T3 or IIOP. Oracle has disclosed only that T3 and IIOP requests can reach a critical function without required authentication; no narrower locus or patch diff is public. Exposure requires network reachability to those protocols on 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0, and successful exploitation yields full server compromise.
