CVE-2026-60400 Overview
CVE-2026-60400 is a high-severity vulnerability in the Admin Server Executable component of Oracle GoldenGate. Affected releases include versions 19.1.0.0.0-19.30.0.0, 21.3-21.21, and 23.4-23.26.1. A low-privileged attacker with network access over HTTPS can exploit the flaw to compromise the GoldenGate instance. Successful exploitation results in full takeover of Oracle GoldenGate, with confirmed impact to confidentiality, integrity, and availability. Oracle addressed the issue in the July 2026 Critical Patch Update.
Critical Impact
Authenticated attackers with only low privileges can take over Oracle GoldenGate over the network, compromising replicated data across enterprise database environments.
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-2026-60400
Vulnerability Analysis
The vulnerability resides in the Admin Server Executable of Oracle GoldenGate, the administrative front-end that manages replication processes, configuration, and deployments. The flaw is reachable over the network via HTTPS, meaning the exposed management interface is the attack surface. Exploitation requires only low privileges, indicating that any authenticated user role on the Admin Server can trigger the condition. Successful exploitation leads to complete takeover of the GoldenGate deployment, with the attacker gaining control equivalent to a full compromise of the service context.
Because GoldenGate replicates data across heterogeneous database systems, a compromised instance can be used to intercept, alter, or halt replication streams. Downstream databases relying on GoldenGate for high availability, migration, or reporting are exposed to secondary attacks. The EPSS score at the time of publication is 0.328% (percentile 25.177), reflecting a currently low predicted exploitation rate.
Root Cause
Oracle has not published root-cause details beyond the July 2026 Critical Patch Update advisory. The affected component is the Admin Server Executable, which handles authenticated HTTPS management requests. See the Oracle Security Alert July 2026 for vendor-provided information.
Attack Vector
The attacker requires network reachability to the GoldenGate Admin Server HTTPS endpoint and a low-privileged account. No user interaction is needed. After authenticating, the attacker sends crafted requests to the Admin Server that result in takeover of the GoldenGate instance. The attack does not require adjacent network positioning or elevated privileges, making internally exposed GoldenGate management interfaces a primary risk.
No public proof-of-concept exploit is available at the time of publication. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2026-60400
Indicators of Compromise
- Unexpected authentication events on the GoldenGate Admin Server from low-privileged accounts followed by administrative actions.
- Creation or modification of Extract, Replicat, or Distribution Path processes outside change-management windows.
- New deployments, credentials, or user roles added to the Service Manager without an approved ticket.
- Outbound network connections from GoldenGate hosts to unknown destinations after Admin Server activity.
Detection Strategies
- Enable and forward Admin Server audit logs, Service Manager logs, and deployment logs to a centralized log platform.
- Correlate HTTPS requests to the Admin Server API endpoints with the identity and role of the calling account.
- Alert on privilege changes, new deployments, and configuration exports issued by non-administrative principals.
Monitoring Recommendations
- Monitor GoldenGate host processes for spawning of unexpected shells, scripting engines, or network utilities.
- Track file changes under GoldenGate deployment directories, including trail files and parameter files.
- Baseline expected administrator source IP ranges and alert on Admin Server logins from outside those ranges.
How to Mitigate CVE-2026-60400
Immediate Actions Required
- Apply the Oracle July 2026 Critical Patch Update to all Oracle GoldenGate deployments in the 19c, 21c, and 23ai release lines.
- Inventory all GoldenGate instances and confirm version numbers against the affected ranges 19.1.0.0.0-19.30.0.0, 21.3-21.21, and 23.4-23.26.1.
- Restrict network access to the Admin Server HTTPS port so that only trusted management hosts can reach it.
- Rotate credentials for all GoldenGate Service Manager and deployment accounts after patching.
Patch Information
Oracle released fixes as part of the July 2026 Critical Patch Update. Refer to the Oracle Security Alert July 2026 for patch identifiers and installation instructions applicable to each affected release train.
Workarounds
- Place the GoldenGate Admin Server behind a management VLAN or VPN accessible only to database administrators.
- Enforce least privilege on GoldenGate roles and remove unused low-privileged accounts that could be abused.
- Require multi-factor authentication on identity providers fronting GoldenGate management access where supported.
# Configuration example: restrict Admin Server access with host firewall (Linux)
# Allow only the management subnet to reach the GoldenGate Admin Server HTTPS port
sudo firewall-cmd --permanent --zone=drop --add-source=0.0.0.0/0
sudo firewall-cmd --permanent --zone=trusted --add-source=10.10.20.0/24
sudo firewall-cmd --permanent --zone=trusted --add-port=9100-9110/tcp
sudo firewall-cmd --reload
