CVE-2026-46931: Oracle EAM Auth Bypass Vulnerability

CVE-2026-46931 Overview

CVE-2026-46931 is a high-severity vulnerability in the Oracle Enterprise Asset Management product of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.6 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this weakness to compromise the application. Successful exploitation results in full takeover of Oracle Enterprise Asset Management, impacting confidentiality, integrity, and availability. The weakness maps to [CWE-284] (Improper Access Control). Oracle published a fix in the June 2026 Critical Patch Update.

Critical Impact

Technical Details for CVE-2026-46931

Vulnerability Analysis

The vulnerability exists in the Internal Operations component of Oracle Enterprise Asset Management, part of the Oracle E-Business Suite. An authenticated attacker holding low privileges can submit crafted HTTP requests to the application. The flaw allows the attacker to bypass access controls and achieve full takeover of the Oracle Enterprise Asset Management instance.

Oracle classifies the issue as easily exploitable, with no user interaction required. Because Enterprise Asset Management often integrates with manufacturing, maintenance, and operational workflows, a compromise can cascade into adjacent E-Business Suite modules. The exploitation does not require chaining additional weaknesses.

The EPSS probability is 0.389% as of 2026-06-18, indicating limited observed exploitation activity at disclosure. No public proof-of-concept exploit is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The underlying issue is improper access control [CWE-284] within the Internal Operations component. Authorization checks fail to adequately restrict actions available to low-privileged users. Oracle has not published technical specifics consistent with its Critical Patch Update disclosure practice.

Attack Vector

The attack is remote over the network using HTTP. The attacker must possess a low-privileged account on the target system. No user interaction is required, and the exploit affects a single security scope. Public exploitation code has not been published.

Detailed technical specifics are restricted under Oracle's vulnerability disclosure policy. Refer to the Oracle Security Alert for the patch matrix and applicability guidance.

Detection Methods for CVE-2026-46931

Indicators of Compromise

Unexpected administrative actions performed by low-privileged accounts within the Oracle Enterprise Asset Management module.
Anomalous HTTP requests to Internal Operations endpoints, especially from users without operational responsibilities for asset management.
New or modified Enterprise Asset Management configurations, work orders, or maintenance records without corresponding change-management tickets.

Detection Strategies

Review Oracle E-Business Suite audit logs for privilege escalation patterns and unusual access to the Internal Operations component.
Inspect web server and application server access logs for repeated HTTP requests targeting Enterprise Asset Management URLs from a single low-privileged session.
Correlate database-level audit records with application-layer activity to identify actions inconsistent with the user's assigned responsibilities.

Monitoring Recommendations

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking for all Enterprise Asset Management responsibilities.
Forward application, web, and database logs to a centralized SIEM for cross-source correlation and historical retention.
Alert on responsibility changes, profile option modifications, and concurrent program submissions originating from accounts outside normal operational baselines.

How to Mitigate CVE-2026-46931

Immediate Actions Required

Apply the June 2026 Oracle Critical Patch Update to all affected Oracle E-Business Suite environments running versions 12.2.6 through 12.2.15.
Inventory all E-Business Suite instances and identify any Enterprise Asset Management deployments exposed to internal or external HTTP access.
Audit user accounts with access to Enterprise Asset Management responsibilities and remove unnecessary low-privileged access pending patching.

Patch Information

Oracle addressed CVE-2026-46931 in the June 2026 Critical Patch Update. Administrators should consult the Oracle Critical Patch Update Advisory - June 2026 for the patch matrix, prerequisites, and deployment guidance specific to their E-Business Suite version.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints using firewalls, VPN, or reverse-proxy allow-lists until patches are applied.
Tighten responsibility assignments so that only required users retain access to Enterprise Asset Management functions.
Increase logging verbosity for the Internal Operations component and review activity daily until remediation is complete.
