CVE-2026-60696Network attack vector

Server takeover via T3 IIOP authentication bypass

Published Aug 18, 2026 · Updated Aug 19, 2026

Authentication bypass in Oracle WebLogic Server allows remote attackers to take over exposed servers via T3 or IIOP. Oracle lists the flaw in the Core component, but the public advisory does not name the vulnerable class, method, or message handler; GitHub maps it to CWE-306, indicating that a critical T3 or IIOP reachable function accepts unauthenticated requests. Exposure requires network reachability to the T3 or IIOP listener on 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, or 15.1.1.0.0, and Oracle rates the result as full server compromise.
