CVE-2026-62562: Oracle HRMS Auth Bypass Vulnerability

CVE-2026-62562 Overview

CVE-2026-62562 is an access control vulnerability in the Oracle HRMS (US) product of Oracle E-Business Suite, specifically within the Internal Operations 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 sensitive Oracle HRMS (US) data. The issue is categorized under [CWE-284] Improper Access Control. Oracle addressed the flaw in its July 2026 Critical Patch Update.

Critical Impact
Successful exploitation results in unauthorized read access to critical Oracle HRMS (US) data, including potential exposure of all data accessible through the affected module.

Affected Products

Oracle E-Business Suite — Oracle HRMS (US) version 12.2.3
Oracle E-Business Suite — Oracle HRMS (US) versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-62562

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of the Oracle HRMS (US) module within Oracle E-Business Suite. An authenticated attacker with low privileges can send crafted HTTP requests to reach functionality that fails to enforce proper access restrictions. The result is disclosure of confidential human resources data managed by the HRMS module.

The issue maps to [CWE-284] Improper Access Control. The affected code path exposes data that should require higher authorization levels or role membership. Because the attack executes over HTTP without user interaction, exploitation can be automated against exposed E-Business Suite deployments.

The EPSS probability is 0.219%, reflecting a low but non-zero likelihood of exploitation activity in the near term. No public proof-of-concept exploit has been observed, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The root cause is missing or insufficient authorization checks within an Internal Operations code path in Oracle HRMS (US). The application evaluates the requester's session but does not fully verify that the caller is entitled to view the targeted HR records or operational data.

Attack Vector

The attack is executed remotely over the network using HTTP requests against the Oracle E-Business Suite web tier. The attacker must possess valid low-privileged credentials to the E-Business Suite instance. No user interaction is required, and the impact is limited to confidentiality — integrity and availability are not affected.

Because no verified public exploit code exists for this CVE, refer to the Oracle Critical Patch Update - July 2026 for authoritative technical detail.

Detection Methods for CVE-2026-62562

Indicators of Compromise

Unusual volumes of HTTP requests from low-privileged E-Business Suite accounts targeting Oracle HRMS (US) Internal Operations endpoints.
Access to HRMS records or reports by user roles that historically have not queried that data.
Anomalous session activity originating from a single account against multiple HR data objects in a short timeframe.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking logs for HRMS Internal Operations URLs.
Correlate application-tier HTTP access logs with database audit trails to identify enumeration of HR records by low-privileged accounts.
Baseline normal role-to-function usage patterns and alert on deviations for HRMS modules.

Monitoring Recommendations

Forward Oracle E-Business Suite application, middle-tier, and database audit logs to a centralized SIEM for correlation and retention.
Monitor for spikes in HRMS-related SQL query volume tied to specific application users.
Track failed and successful authorization decisions on HRMS Internal Operations functions to surface probing activity.

How to Mitigate CVE-2026-62562

Immediate Actions Required

Apply the Oracle July 2026 Critical Patch Update to all Oracle E-Business Suite instances running Oracle HRMS (US) versions 12.2.3 through 12.2.15.
Inventory all E-Business Suite deployments and confirm version and patch level before scheduling maintenance windows.
Review recent access logs against HRMS Internal Operations functionality for signs of exploitation prior to patching.

Patch Information

Oracle released fixes for this vulnerability in the July 2026 Critical Patch Update. Full patch numbering, prerequisites, and installation guidance are documented in the Oracle Critical Patch Update Advisory - July 2026. Administrators should follow Oracle's standard E-Business Suite patching procedures, including AutoConfig runs and post-patch validation.

Workarounds

Restrict network access to the Oracle E-Business Suite web tier so that only trusted internal users and networks can reach HRMS functionality.
Review and tighten responsibilities and menu assignments so that low-privileged accounts cannot invoke HRMS Internal Operations functions.
Enforce multi-factor authentication and strong credential hygiene on all E-Business Suite user accounts to raise the barrier to exploitation.
