CVE-2026-47056 Overview
CVE-2026-47056 is a critical authentication bypass vulnerability in the REST Service component of Oracle Data Integrator, part of Oracle Fusion Middleware. The flaw affects supported versions 12.2.1.4.0 and 14.1.2.0.0. An unauthenticated attacker with network access via HTTP can compromise Oracle Data Integrator without user interaction. The vulnerability carries a maximum CVSS 3.1 Base Score of 10.0 due to the scope change, meaning successful exploitation extends impact beyond Oracle Data Integrator itself. The root weakness is classified as [CWE-306] Missing Authentication for Critical Function.
Critical Impact
Unauthenticated remote attackers can take over Oracle Data Integrator and pivot to additional Fusion Middleware components, achieving full compromise of confidentiality, integrity, and availability.
Affected Products
- Oracle Data Integrator 12.2.1.4.0
- Oracle Data Integrator 14.1.2.0.0
- Oracle Fusion Middleware (REST Service component)

Technical Details for CVE-2026-47056
Vulnerability Analysis
The vulnerability resides in the REST Service component of Oracle Data Integrator. The service exposes functionality over HTTP without enforcing authentication on critical operations. An attacker who can reach the REST endpoint on the network can invoke privileged actions directly. Because the scope changes on exploitation, the attacker's impact is not confined to the vulnerable component. Adjacent Fusion Middleware services and data flows managed by Oracle Data Integrator can be manipulated or accessed. Successful exploitation results in complete takeover of the Data Integrator instance.
Root Cause
The root cause is [CWE-306] Missing Authentication for Critical Function. The affected REST endpoints accept requests without verifying the caller's identity or session. Because Oracle Data Integrator orchestrates ETL and integration jobs across systems, the missing check exposes credentials, data flows, and downstream systems that the integrator connects to.
Attack Vector
Exploitation is remote, network-based, and requires no privileges or user interaction. An attacker sends crafted HTTP requests to the exposed REST Service. Because the requests bypass authentication, the attacker can invoke administrative operations, execute integration tasks, read sensitive configuration, and reach connected data sources. Public exploit code is not currently listed in CISA KEV or ExploitDB, but the low attack complexity and network reachability make weaponization straightforward once technical details circulate.
No verified proof-of-concept code is available at this time. Refer to the Oracle Security Alert July 2026 for vendor technical details.
Detection Methods for CVE-2026-47056
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle Data Integrator REST endpoints originating from unexpected source addresses.
- New or modified integration jobs, agents, or scenarios created outside of change-management windows.
- Unexpected outbound connections from the Data Integrator host to systems it does not normally reach.
- Access to credential stores or topology configurations without corresponding administrator login events.
Detection Strategies
- Inspect web access logs for POST and GET requests to Data Integrator REST paths lacking valid authorization headers.
- Correlate REST API activity with authentication events; requests processed without a preceding successful auth are suspicious.
- Baseline normal REST traffic volume and alert on anomalous spikes or new client IPs.
- Monitor process and network telemetry on Fusion Middleware hosts for spawned shells or non-standard child processes of the WebLogic managed server.
Monitoring Recommendations
- Enable verbose access logging on the WebLogic managed server hosting Oracle Data Integrator.
- Forward middleware, OS, and network logs to a centralized SIEM for correlation across Fusion Middleware components.
- Alert on modifications to ODI repository schemas, agent registrations, and REST service configuration files.
How to Mitigate CVE-2026-47056
Immediate Actions Required
- Apply the July 2026 Critical Patch Update from Oracle to all Oracle Data Integrator 12.2.1.4.0 and 14.1.2.0.0 deployments.
- Restrict network access to Oracle Data Integrator REST endpoints to trusted management networks only.
- Audit the ODI repository, agents, and topology for unauthorized changes created before the patch was applied.
- Rotate credentials stored in ODI topology, including database, LDAP, and cloud connector accounts.
Patch Information
Oracle addresses CVE-2026-47056 in the Oracle Security Alert July 2026 Critical Patch Update. Administrators should download the patch corresponding to the exact ODI version deployed and apply it following Oracle's Fusion Middleware patching procedures.
Workarounds
- Place the Oracle Data Integrator REST Service behind a reverse proxy or WAF that enforces authentication before requests reach the backend.
- Disable the REST Service component if it is not required for business operations.
- Apply network ACLs on the WebLogic listen ports to allow only known integration clients.
# Example: restrict REST endpoint access with iptables until the patch is applied
iptables -A INPUT -p tcp --dport 15101 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 15101 -j DROP
