CVE-2026-60899: Oracle HCM Info Disclosure Vulnerability

CVE-2026-60899 Overview

CVE-2026-60899 is a vulnerability in the Oracle HCM Configuration Workbench product of Oracle E-Business Suite, specifically in the Rapid Implementation component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the vulnerability to gain unauthorized access to critical data or complete access to all Oracle HCM Configuration Workbench accessible data. The vulnerability impacts confidentiality only, with no integrity or availability impact. Oracle disclosed the issue in the Oracle Security Alert July 2026.

Critical Impact
Authenticated network attackers can read all data accessible to Oracle HCM Configuration Workbench, exposing sensitive human capital management records.

Technical Details for CVE-2026-60899

Vulnerability Analysis

The vulnerability resides in the Rapid Implementation component of Oracle HCM Configuration Workbench, a module used to configure human capital management deployments in Oracle E-Business Suite. Oracle classifies the issue as easily exploitable over HTTP by an attacker holding low privileges within the application. Successful exploitation results in unauthorized read access to critical or all data accessible through the workbench.

Only confidentiality is affected. The attacker cannot modify data or degrade availability through this flaw alone. However, HCM data commonly includes personally identifiable information, compensation records, and organizational structures, making disclosure impactful. Oracle addressed the issue in the July 2026 Critical Patch Update cycle.

Root Cause

Oracle has not published detailed root-cause analysis. Based on the CVSS metrics and the affected component, the flaw allows a user with valid but limited application credentials to bypass authorization checks within the Rapid Implementation workflows. The scope remains unchanged, indicating the vulnerability is contained to the vulnerable component.

Attack Vector

Exploitation requires network reachability to the Oracle E-Business Suite HTTP interface and a low-privileged authenticated account. No user interaction is required. Attack complexity is low, meaning the attacker does not depend on race conditions or environmental preconditions. Refer to the Oracle Security Alert July 2026 for the vendor's technical summary.

No verified public exploit code is available at this time. The vulnerability mechanism should be reviewed through the Oracle advisory rather than reconstructed from synthetic proof-of-concept code.

Detection Methods for CVE-2026-60899

Indicators of Compromise

Unusual HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Rapid Implementation endpoints in the HCM Configuration Workbench.
Access patterns showing bulk retrieval of HCM configuration or reference data by accounts that do not normally exercise those functions.
Session activity from user accounts outside of standard business hours accessing HCM Configuration Workbench URLs.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to correlate low-privileged account activity with HCM Configuration Workbench endpoints.
Baseline expected user roles for the Rapid Implementation module and alert on access from any account outside that baseline.
Correlate web server access logs with application-layer identity to identify authenticated data enumeration.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database audit, and web tier logs to a centralized analytics platform for retention and correlation.
Alert on spikes in response payload size from HCM Configuration Workbench URLs, which may indicate mass data extraction.
Track failed and successful authentication events for HCM-scoped accounts and flag anomalies.

How to Mitigate CVE-2026-60899

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
Inventory all Oracle HCM Configuration Workbench deployments and confirm patch status across production, staging, and disaster recovery environments.
Review and reduce the population of accounts granted access to the HCM Configuration Workbench module.
Restrict network exposure of the Oracle E-Business Suite HTTP interface to trusted networks pending patch deployment.

Patch Information

Oracle released fixes for CVE-2026-60899 as part of the Oracle Security Alert July 2026. Administrators should follow Oracle's standard Critical Patch Update installation procedure for E-Business Suite 12.2.x, including pre-patch backups and post-patch functional validation of HCM workflows.

Workarounds

Remove or reduce role assignments that grant access to the Rapid Implementation component for users who do not require it.
Place the Oracle E-Business Suite HTTP endpoints behind a web application firewall configured to restrict access to the HCM Configuration Workbench paths.
Enforce network segmentation so that only jump hosts or VPN-authenticated administrators can reach the affected HTTP interfaces.

bash

# Example: restrict access to HCM Configuration Workbench paths at the reverse proxy
# Replace <allowed_cidr> with your administrative network range
location /OA_HTML/ {
    allow <allowed_cidr>;
    deny all;
    proxy_pass http://ebs_backend;
}
