CVE-2026-61079 Overview
CVE-2026-61079 affects Oracle GoldenGate in the Libraries component. The flaw impacts supported versions 19.1.0.0.0-19.30.0.0, 21.3-21.21, and 23.4-23.26.2. A high-privileged attacker with local logon access to the infrastructure hosting Oracle GoldenGate can exploit the vulnerability. Successful exploitation requires interaction from a user other than the attacker. The result is unauthorized access to critical data, limited unauthorized modification of accessible data, and a complete denial-of-service condition against Oracle GoldenGate.
Critical Impact
Local exploitation yields full read access to Oracle GoldenGate data, partial write access, and a repeatable crash of the service.
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 23.26.2

Technical Details for CVE-2026-61079
Vulnerability Analysis
The vulnerability resides in the Libraries component of Oracle GoldenGate, Oracle's real-time data replication and integration platform. Exploitation is difficult and requires the attacker to already hold high privileges and possess local logon access to the host running Oracle GoldenGate. The attack additionally depends on a separate user performing an action the attacker cannot trigger alone.
When successfully abused, the flaw exposes all Oracle GoldenGate accessible data to the attacker. The attacker also gains the ability to insert, update, or delete a subset of accessible data. The condition further enables a hang or repeatable crash of the GoldenGate service, producing a complete denial of service. Oracle categorizes the impact as affecting confidentiality, integrity, and availability.
Root Cause
Oracle has not published detailed root-cause information beyond identifying the affected Libraries component. The advisory indicates the code path is reachable only through local infrastructure access combined with elevated privileges and secondary user interaction. Refer to the Oracle Security Alert July 2026 for vendor-provided detail.
Attack Vector
The attack vector is local. An authenticated administrator or equivalent high-privileged principal with a shell or session on the GoldenGate host stages the exploitation. The scenario then requires an unrelated user to interact with a crafted artifact, control channel, or workflow. The scope remains unchanged, meaning the impact is confined to the vulnerable Oracle GoldenGate component. No public proof-of-concept, exploit code, or in-the-wild exploitation has been reported for this CVE.
Detection Methods for CVE-2026-61079
Indicators of Compromise
- Unexpected crashes, hangs, or restart loops of Oracle GoldenGate ggsci, Extract, or Replicat processes on affected hosts.
- Anomalous file creation or modification within GoldenGate library directories by high-privileged local accounts.
- Interactive logons by privileged operators followed by unusual GoldenGate configuration changes.
Detection Strategies
- Correlate local privileged logons on GoldenGate hosts with subsequent GoldenGate process failures or configuration mutations.
- Monitor integrity of GoldenGate installation directories and libraries with file integrity monitoring against a known-good baseline.
- Audit GoldenGate report and discard files for unexpected large reads, replication anomalies, or repeated abnormal terminations.
Monitoring Recommendations
- Forward Oracle GoldenGate error, report, and discard logs to a centralized SIEM for retention and correlation.
- Alert on repeated abnormal exits of GoldenGate manager, Extract, or Replicat processes within short time windows.
- Track privileged shell activity on GoldenGate infrastructure hosts and require session recording for administrators.
How to Mitigate CVE-2026-61079
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update fixes for Oracle GoldenGate to all affected versions.
- Inventory GoldenGate deployments and confirm running versions against the affected ranges 19.1.0.0.0-19.30.0.0, 21.3-21.21, and 23.4-23.26.2.
- Restrict interactive and remote logon on GoldenGate hosts to a minimal set of administrators.
Patch Information
Oracle issued fixes for CVE-2026-61079 as part of its July 2026 Critical Patch Update. Details, patch identifiers, and download locations are published in the Oracle Security Alert July 2026. Administrators should follow Oracle's documented upgrade procedures and validate replication topologies after patching.
Workarounds
- Enforce least-privilege on all accounts capable of logging on to GoldenGate infrastructure until patches are applied.
- Require multi-party approval and session recording for privileged administrative actions on GoldenGate hosts.
- Segment GoldenGate servers on isolated management networks to reduce exposure of local logon paths.
