CVE-2026-47022: Oracle GoldenGate Stream Analytics DOS Flaw

CVE-2026-47022 Overview

CVE-2026-47022 is a local denial of service vulnerability in the Security component of Oracle GoldenGate Stream Analytics. The affected version is 26.1.0.0.0. A low-privileged attacker with logon access to the infrastructure where GoldenGate Stream Analytics runs can exploit this flaw to cause a partial denial of service. The vulnerability maps to CWE-400: Uncontrolled Resource Consumption and affects availability only. Oracle disclosed the issue in the July 2026 Critical Patch Update advisory.

Critical Impact
An authenticated local attacker can trigger a partial denial of service in GoldenGate Stream Analytics, reducing availability of streaming data pipelines that depend on the service.

Affected Products

Technical Details for CVE-2026-47022

Vulnerability Analysis

The flaw resides in the Security component of Oracle GoldenGate Stream Analytics 26.1.0.0.0. An attacker who already holds a low-privileged local account on the host running the service can trigger conditions that degrade availability. Oracle classifies the outcome as a partial denial of service, meaning the service may become unresponsive or degraded without a full outage.

The CWE-400 classification indicates uncontrolled resource consumption. The vulnerable code path likely fails to bound resource usage when handling attacker-influenced input from an authenticated local session. Confidentiality and integrity are not affected. The EPSS probability is 0.132%, reflecting the local attack requirement and limited public exploitation interest.

Root Cause

The root cause is uncontrolled resource consumption in the GoldenGate Stream Analytics Security component. The component does not adequately limit the allocation or lifecycle of a resource that a local, authenticated actor can influence. Oracle has not published implementation-level details in the public advisory.

Attack Vector

Exploitation requires local access with valid low-privileged credentials on the host. No user interaction is required, and the attack complexity is low. The scope is unchanged, and only the availability of GoldenGate Stream Analytics is impacted. Remote network exploitation is not applicable.

No public proof-of-concept code or exploit is available. Readers should consult the Oracle Security Alert July 2026 advisory for authoritative technical details.

Detection Methods for CVE-2026-47022

Indicators of Compromise

Unexpected termination, hangs, or restart events of GoldenGate Stream Analytics processes on hosts running version 26.1.0.0.0.
Sustained resource saturation (CPU, memory, threads, or file descriptors) on the Stream Analytics host without corresponding legitimate workload.
Local session activity from low-privileged accounts immediately preceding service degradation.

Detection Strategies

Correlate local logon events with process crashes or resource spikes on GoldenGate Stream Analytics hosts.
Monitor Stream Analytics application logs for exceptions, thread pool exhaustion, or repeated component restarts in the Security module.
Baseline normal resource utilization for the service and alert on statistically significant deviations.

Monitoring Recommendations

Enable OS-level auditing of local logons and process activity on hosts that run Oracle GoldenGate Stream Analytics.
Forward Stream Analytics logs and host telemetry into a centralized analytics platform for correlation with authentication events.
Alert on service availability metrics and health probes to detect partial denial of service conditions quickly.

How to Mitigate CVE-2026-47022

Immediate Actions Required

Apply the fixes described in the Oracle Security Alert July 2026 Critical Patch Update to all Oracle GoldenGate Stream Analytics 26.1.0.0.0 deployments.
Inventory hosts running the affected version and confirm patch status through configuration management.
Review and reduce the number of accounts with local logon rights to Stream Analytics infrastructure.

Patch Information

Oracle addressed CVE-2026-47022 in the July 2026 Critical Patch Update. Administrators should download and apply the vendor-supplied patch for GoldenGate Stream Analytics 26.1.0.0.0 following the guidance in the Oracle Security Alert July 2026 advisory.

Workarounds

Restrict local shell and interactive logon on Stream Analytics hosts to a minimal set of trusted administrators.
Enforce least privilege for service and operational accounts that interact with the Stream Analytics host.
Apply operating system resource controls (cgroups, ulimits) to constrain per-user resource consumption where compatible with the service.

bash

# Configuration example: restrict per-user resource usage via /etc/security/limits.d/goldengate.conf
# Replace <user> with the low-privileged account name
<user>  hard  nproc     256
<user>  hard  nofile    1024
<user>  hard  as        1048576
