CVE-2026-60398 Overview
CVE-2026-60398 is a high-severity vulnerability affecting Oracle GoldenGate Microservices. The flaw allows a low-privileged attacker with network access via HTTP to compromise Oracle GoldenGate. Successful exploitation results in complete takeover of the affected instance, impacting confidentiality, integrity, and availability.
Oracle disclosed this vulnerability in the Oracle Security Alert July 2026. The vulnerability affects multiple supported branches of Oracle GoldenGate deployed in enterprise data replication environments.
Critical Impact
An authenticated attacker with minimal privileges can achieve full takeover of Oracle GoldenGate over the network with no user interaction required.
Affected Products
- Oracle GoldenGate 19.1.0.0.0 through 19.30.0.0
- Oracle GoldenGate 21.3 through 21.21
- Oracle GoldenGate 23.4 through 23.26.1

Technical Details for CVE-2026-60398
Vulnerability Analysis
The vulnerability resides in the Oracle GoldenGate Microservices component, which provides a REST-based architecture for managing GoldenGate deployments. GoldenGate Microservices exposes HTTP endpoints for administration, monitoring, and data replication configuration.
An attacker with low-level authenticated access can send crafted HTTP requests to compromise the service. The exploitation path requires no user interaction and can be performed remotely over the network. The scope remains unchanged, but the attacker gains high impact on confidentiality, integrity, and availability, consistent with full service takeover.
Oracle GoldenGate frequently handles sensitive replication streams across production databases. A takeover enables attackers to intercept replicated data, alter records in transit, or disrupt data pipelines feeding downstream systems.
Root Cause
Oracle has not published detailed root cause information. Based on the CVSS metrics and takeover impact, the flaw likely stems from insufficient authorization enforcement or input validation within one or more Microservices HTTP endpoints. Refer to the Oracle Security Alert July 2026 for vendor-supplied details.
Attack Vector
The attack vector is network-based over HTTP. An attacker requires a valid low-privileged account on the target GoldenGate deployment. From there, the attacker issues HTTP requests to Microservices endpoints such as the Administration Service, Distribution Service, or Receiver Service. Successful exploitation escalates control to full takeover of the GoldenGate instance.
The EPSS score is 0.447%, reflecting low current probability of observed exploitation activity, though the takeover impact warrants prioritized remediation.
Detection Methods for CVE-2026-60398
Indicators of Compromise
- Unexpected HTTP requests to GoldenGate Microservices management endpoints (Administration Server, Distribution Server, Receiver Server, Performance Metrics Server) from unusual source IPs.
- New or modified extract, replicat, or distribution path configurations that were not initiated by administrators.
- Anomalous authentication events for low-privileged GoldenGate accounts followed by privileged administrative actions.
Detection Strategies
- Review GoldenGate Microservices audit logs for privilege changes, credential store modifications, and configuration deployments performed by non-admin accounts.
- Correlate HTTP access logs from the GoldenGate reverse proxy (NGINX) with authentication events to identify low-privileged sessions performing sensitive operations.
- Alert on outbound connections from GoldenGate hosts to unknown targets, which may indicate a hijacked distribution path.
Monitoring Recommendations
- Enable and centralize GoldenGate Microservices REST API access logs and forward to a SIEM for correlation.
- Monitor process activity on GoldenGate hosts for unexpected child processes spawned by oggca, ServiceManager, or related binaries.
- Baseline normal replication topology and alert on unauthorized changes to extract or replicat parameter files.
How to Mitigate CVE-2026-60398
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update to all affected GoldenGate 19c, 21c, and 23ai deployments as documented in the Oracle Security Alert July 2026.
- Inventory all Oracle GoldenGate Microservices instances, including versions 19.1.0.0.0-19.30.0.0, 21.3-21.21, and 23.4-23.26.1, and prioritize internet-exposed deployments.
- Rotate credentials for all GoldenGate user accounts, especially low-privileged accounts that could be leveraged for exploitation.
Patch Information
Oracle addressed CVE-2026-60398 in the July 2026 Critical Patch Update. Administrators should download the appropriate Release Update or Bundle Patch for their GoldenGate version from My Oracle Support and follow the vendor-supplied installation instructions. Restart of the GoldenGate Service Manager and dependent Microservices is required for the patch to take effect.
Workarounds
- Restrict network access to GoldenGate Microservices HTTP/HTTPS ports using firewalls or security groups, allowing only trusted administrative networks.
- Enforce least privilege in the GoldenGate role model and remove unnecessary low-privileged accounts until patching is complete.
- Place GoldenGate Microservices behind a reverse proxy with strict authentication and request filtering to reduce exposure of vulnerable endpoints.
# Example: Restrict access to GoldenGate Microservices ports with iptables
# Replace 10.0.0.0/24 with your trusted admin network
iptables -A INPUT -p tcp --dport 9100:9110 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 9100:9110 -j DROP
# Verify GoldenGate Microservices version
cd $OGG_HOME/bin
./ggsci -v
