CVE-2026-46906: JD Edwards EnterpriseOne Auth Bypass

CVE-2026-46906 Overview

CVE-2026-46906 is an access control vulnerability [CWE-284] in Oracle JD Edwards EnterpriseOne Tools, affecting the Enterprise Infrastructure Security component. Supported versions 9.2.0.0 through 9.2.26.2 are affected. A low-privileged attacker with network access via HTTP can compromise the product without user interaction. The flaw involves a scope change, meaning successful exploitation impacts resources beyond the vulnerable component itself. Successful attacks result in unauthorized creation, deletion, or modification of all accessible data, plus unauthorized read access to critical data across JD Edwards EnterpriseOne Tools.

Critical Impact
Authenticated attackers can read, modify, and delete all data accessible to JD Edwards EnterpriseOne Tools over HTTP, with impact extending to additional products via scope change.

Affected Products

Oracle JD Edwards EnterpriseOne Tools 9.2.0.0 through 9.2.26.2

Technical Details for CVE-2026-46906

Vulnerability Analysis

The vulnerability resides in the Enterprise Infrastructure Security component of Oracle JD Edwards EnterpriseOne Tools. It is classified under [CWE-284] (Improper Access Control), indicating that the product fails to properly restrict access to a resource from unauthorized actors. The attack reaches the system over HTTP, requires only low privileges, and needs no user interaction.

Because exploitation triggers a scope change, the impact extends beyond JD Edwards EnterpriseOne Tools itself. Attackers can compromise data and functionality in additional Oracle products that trust or integrate with the affected component. Successful attacks compromise both confidentiality and integrity at a high level, while availability remains unaffected.

The Exploit Prediction Scoring System rates this issue at 0.326% (24.199 percentile), and there is no public proof-of-concept at the time of publication.

Root Cause

The root cause is improper enforcement of access controls within the Enterprise Infrastructure Security component. Authorization checks do not adequately validate that the requesting low-privileged account has permission to perform the requested operation against the targeted resource. As a result, an authenticated user can reach administrative or cross-tenant data paths intended for higher-privileged roles.

Attack Vector

The attack vector is network-based over HTTP. An attacker authenticates with any low-privileged account that has access to the JD Edwards EnterpriseOne Tools interface. The attacker then issues crafted HTTP requests to functionality protected by insufficient authorization checks. Because Oracle has not released exploit-specific technical details, refer to the Oracle Critical Patch Update Advisory - June 2026 for vendor guidance.

Detection Methods for CVE-2026-46906

Indicators of Compromise

Unexpected HTTP requests from low-privileged JD Edwards user accounts to administrative or security-configuration endpoints.
Audit log entries showing data create, modify, or delete actions performed by accounts that should not hold those permissions.
Anomalous read access to sensitive business records or security objects outside the user's normal role scope.
Authentication events from low-privileged accounts followed by elevated activity in dependent Oracle products.

Detection Strategies

Compare HTTP access logs against the role-based access control matrix to identify operations performed outside an account's authorized scope.
Monitor JD Edwards audit tables for high-volume create, update, or delete operations executed by non-administrative users.
Correlate authentication events across JD Edwards EnterpriseOne Tools and downstream Oracle products to detect scope-change exploitation.

Monitoring Recommendations

Enable verbose HTTP request logging on JD Edwards EnterpriseOne web servers and forward logs to a centralized SIEM.
Alert on access to Enterprise Infrastructure Security endpoints by accounts outside the security administrator group.
Baseline normal user activity per role and flag deviations involving privileged operations.

How to Mitigate CVE-2026-46906

Immediate Actions Required

Apply the Oracle Critical Patch Update from June 2026 to all JD Edwards EnterpriseOne Tools instances on versions 9.2.0.0 through 9.2.26.2.
Inventory JD Edwards user accounts and disable or reduce privileges for any unused low-privileged accounts that can reach the affected HTTP endpoints.
Restrict network access to the JD Edwards EnterpriseOne Tools HTTP interface to trusted management networks until patching completes.

Patch Information

Oracle addressed this vulnerability in the June 2026 Critical Patch Update. Administrators must download and apply the relevant JD Edwards EnterpriseOne Tools update referenced in the Oracle Security Alert. Verify the post-patch tools release is above 9.2.26.2.

Workarounds

Place the JD Edwards EnterpriseOne Tools web tier behind a reverse proxy or web application firewall that restricts access to authenticated administrative URLs by source IP.
Enforce strict role separation and remove unnecessary entitlements from low-privileged JD Edwards accounts.
Increase audit log retention and review frequency for the Enterprise Infrastructure Security component until the patch is applied.

bash

# Example: restrict HTTP access to JD Edwards admin paths at the reverse proxy
# (nginx) - allow only the security administration subnet
location /jde/security/ {
    allow 10.10.50.0/24;
    deny all;
    proxy_pass http://jde-backend;
}
