On September 15, 2026, Oracle released its September Critical Security Patch Update with 673 fixes across 17 product families, including several unauthenticated remote takeovers of WebLogic Server. Inventory every exposed WebLogic instance and cut T3/IIOP before a diffable exploit turns your servers into a target.

CVE-2026-21962, a CVSS 10.0 access-control flaw in Oracle’s WebLogic Server proxy plug-in that was fixed in the January 2026 CPU, landed in CISA’s KEV catalog on August 24 with confirmed active exploitation. Apply the January patch before August 27 and inventory your middleware tier, which vulnerability scans too often miss.

On August 5, 2026, Huntress researchers documented an attack where the khunt toolkit was compiled and executed inside an Oracle database via SQL injection on an Apache Tomcat endpoint. Attackers abused Oracle's embedded JVM to run OS commands with SYSTEM privileges, steal Windows hashes, and map the network. The message to DBAs is clear: your database is a full Java runtime — treat it like one.
