Server takeover via undisclosed T3 IIOP flaw
Published Aug 18, 2026 · Updated Aug 20, 2026
Remote compromise in Oracle WebLogic Server allows remote attackers to take over the server via T3 or IIOP on affected versions. Oracle has not disclosed the vulnerable Core code path or the unsafe operation on T3 or IIOP input, so the public record does not identify the exact flaw. Exposure requires network reachability to the T3 or IIOP listeners; Oracle lists 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0 as affected, and successful exploitation yields full confidentiality, integrity, and availability impact on the WebLogic instance.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
