CVE-2026-60320 Overview
CVE-2026-60320 affects the Oracle Data Integrator product within Oracle Fusion Middleware, specifically the Patchset Assistant component. Supported versions 12.2.1.4.0 and 14.1.2.0.0 are affected. An unauthenticated attacker with network access via HTTP can exploit this vulnerability without user interaction or elevated privileges. Successful exploitation results in unauthorized access to critical data or complete access to all Oracle Data Integrator accessible data. The vulnerability impacts confidentiality only, with no integrity or availability impact per the published CVSS vector.
Critical Impact
Remote, unauthenticated attackers can extract sensitive data from Oracle Data Integrator deployments over HTTP without any user interaction.

Technical Details for CVE-2026-60320
Vulnerability Analysis
The flaw resides in the Patchset Assistant component of Oracle Data Integrator, part of the wider Oracle Fusion Middleware suite. Oracle Data Integrator (ODI) is a data integration platform used to build and manage complex data warehouses and ETL workflows. The Patchset Assistant is the utility responsible for applying and validating patchsets against ODI repositories and installations.
An unauthenticated attacker reaching the affected service over HTTP can obtain unauthorized read access to data managed or exposed by ODI. Oracle categorizes the outcome as unauthorized access to critical data or complete access to all ODI-accessible data, aligning with an information disclosure classification. The vulnerability does not permit modification of data or disruption of service, per the vendor-supplied CVSS metrics.
Root Cause
Oracle has not published detailed root cause analysis in the public advisory. Based on the vendor description, the defect enables data retrieval without authentication, indicating missing or improperly enforced access controls on an HTTP-accessible interface within the Patchset Assistant component.
Attack Vector
Exploitation requires only network reachability to the affected HTTP endpoint. No credentials, user interaction, or prior foothold are required. Attackers targeting internet-exposed or lateral-accessible ODI deployments can issue crafted HTTP requests to retrieve sensitive integration metadata, connection details, or repository contents. Refer to the Oracle Security Alert - July 2026 for the vendor's technical details.
Detection Methods for CVE-2026-60320
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle Data Integrator Patchset Assistant endpoints originating from unexpected sources.
- Large or repeated HTTP response payloads returned to unauthenticated clients from ODI hosts.
- Anomalous outbound data transfer volumes from ODI servers following inbound HTTP scans.
Detection Strategies
- Inventory all Oracle Data Integrator installations and confirm whether they run version 12.2.1.4.0 or 14.1.2.0.0.
- Review web server and application logs on ODI middleware tier hosts for anonymous requests to Patchset Assistant URIs.
- Correlate HTTP access logs with authentication logs to identify request patterns lacking session context.
Monitoring Recommendations
- Enable verbose HTTP access logging on WebLogic servers hosting ODI and forward logs to a centralized SIEM.
- Alert on HTTP 200 responses to unauthenticated requests targeting administrative or patch-related URIs.
- Monitor egress traffic from ODI hosts for spikes indicative of bulk data exfiltration.
How to Mitigate CVE-2026-60320
Immediate Actions Required
- Apply the fixes shipped in the Oracle Critical Patch Update - July 2026 to all affected ODI instances.
- Restrict network exposure of Oracle Data Integrator management and HTTP interfaces to trusted administrative networks only.
- Audit ODI repository contents and downstream systems for evidence of unauthorized data access.
Patch Information
Oracle addressed CVE-2026-60320 in the July 2026 Critical Patch Update. Administrators running Oracle Data Integrator 12.2.1.4.0 or 14.1.2.0.0 should apply the corresponding patchset immediately. The vendor advisory is available at the Oracle Security Alert - July 2026.
Workarounds
- Place affected ODI HTTP endpoints behind a reverse proxy or WAF that enforces authentication and IP allow-listing.
- Disable or firewall the Patchset Assistant interface when it is not actively required for maintenance operations.
- Segment ODI hosts into a restricted management VLAN with no direct internet exposure until patching completes.
# Example: restrict ODI HTTP listener to trusted admin subnet using iptables
iptables -A INPUT -p tcp --dport 8001 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8001 -j DROP
