CriticalVulnerabilityCVE-2026-91233updated 25 Oct 2026, 18:35 UTC

Oracle SOA Suite can be fully taken over over the network without login

Someone on the network who does not need a password could gain full control of the Oracle SOA Suite server and read, change, or break its data and services. Anyone who can reach the service over the network is a potential attacker.

How the attack works simplified

  1. 1Attacker on networkNo login or credentials needed
  2. 2Crafted SOAP requestSent to the SOA Suite endpoint
  3. 3Enterprise Scheduling flawRequest is processed without authentication
  4. 4Server compromisedAttacker gains control of the service
  5. ResultAttacker takes over the SOA Suite

What happened

A flaw in the Enterprise Scheduling System component of Oracle SOA Suite (Oracle Fusion Middleware) lets an unauthenticated attacker with network access send crafted SOAP requests to compromise the product.

Why it is dangerous: A successful attack can lead to complete takeover of the SOA Suite server, affecting confidentiality, integrity, and availability. Organizations that run this middleware and expose its SOAP endpoints are at risk.

Are you affected?

You are affected if you run Oracle SOA Suite 12.2.1.4.0 or 14.1.2.0.0 with the Enterprise Scheduling System component reachable over the network via SOAP.

Oracle SOA Suite 12.2.1.4.0; Oracle SOA Suite 14.1.2.0.0

What to do

  1. Check whether your Oracle SOA Suite runs version 12.2.1.4.0 or 14.1.2.0.0 with Enterprise Scheduling System enabled
  2. Restrict network access to the SOAP endpoints of the SOA Suite to trusted hosts only
  3. Apply the security update or patch from Oracle as soon as it is available for your version
