CVE-2026-46913: Oracle JD Edwards Auth Bypass Flaw

CVE-2026-46913 Overview

CVE-2026-46913 is a vulnerability in the Installation Security component of Oracle JD Edwards EnterpriseOne Tools. The flaw affects supported versions 9.2.0.0 through 9.2.26.2. An unauthenticated attacker with logon access to the infrastructure where JD Edwards EnterpriseOne Tools executes can exploit the weakness to take over the product. The vulnerability carries a scope change, meaning successful attacks can impact additional products beyond JD Edwards EnterpriseOne Tools. Oracle classifies the issue under CWE-284: Improper Access Control and addresses it in the Oracle Security Alert Advisory - CVE-2026-46913.

Critical Impact
Successful exploitation results in complete takeover of JD Edwards EnterpriseOne Tools with confidentiality, integrity, and availability impacts extending to adjacent components.

Affected Products

Oracle JD Edwards EnterpriseOne Tools 9.2.0.0 through 9.2.26.2
Installation Security component of JD Edwards EnterpriseOne Tools

Technical Details for CVE-2026-46913

Vulnerability Analysis

The vulnerability resides in the Installation Security component of Oracle JD Edwards EnterpriseOne Tools. An attacker who can authenticate to the host infrastructure but lacks application credentials can compromise JD Edwards EnterpriseOne Tools. Oracle describes the issue as easily exploitable and notes that successful attacks expand beyond the vulnerable product through a scope change. The result is full takeover of the affected component, with cascading impact across integrated systems. The weakness is categorized as Improper Access Control [CWE-284], indicating that installation-time security boundaries are not properly enforced.

Root Cause

The root cause is improper enforcement of access controls within the installation security logic. Components installed or configured by the Tools layer do not adequately restrict who can interact with privileged installation primitives. A local actor with host logon rights can leverage this gap to escalate control of the application stack without supplying application-layer credentials.

Attack Vector

Exploitation requires local access to the infrastructure hosting JD Edwards EnterpriseOne Tools. The attacker does not need application authentication or user interaction. Because the vulnerability triggers a scope change, the impact crosses the security boundary of the vulnerable component and reaches additional resources managed by or trusting the Tools layer. The current EPSS probability is 0.156% (percentile 5.07), reflecting low predicted exploitation activity at this time.

No public proof-of-concept code or verified exploit samples are available. Refer to the Oracle Security Alert for vendor-supplied technical context.

Detection Methods for CVE-2026-46913

Indicators of Compromise

Unexpected modifications to JD Edwards EnterpriseOne Tools installation directories, configuration files, or service binaries.
New or modified privileged accounts on hosts running EnterpriseOne Tools versions 9.2.0.0 through 9.2.26.2.
Anomalous local logons followed by execution of JD Edwards installer or administrative utilities outside normal change windows.

Detection Strategies

Inventory JD Edwards EnterpriseOne Tools hosts and identify any instance running versions 9.2.0.0 through 9.2.26.2.
Audit local user sessions on Tools servers and correlate them with installation or configuration activity.
Review file integrity monitoring data for changes to installation security artifacts and service definitions.

Monitoring Recommendations

Forward authentication, process, and file events from JD Edwards hosts to a centralized analytics platform.
Alert on local logons to JD Edwards Tools servers from accounts that do not normally administer the platform.
Track child processes spawned by JD Edwards installer or service binaries for unexpected command execution.

How to Mitigate CVE-2026-46913

Immediate Actions Required

Apply the fixes published in the Oracle Security Alert Advisory for JD Edwards EnterpriseOne Tools.
Restrict interactive and remote logon rights on JD Edwards Tools infrastructure to a minimal set of administrators.
Audit existing installations to confirm version status and identify any unauthorized configuration changes.

Patch Information

Oracle published mitigations through its security alert program. Administrators should review the Oracle Security Alert Advisory - CVE-2026-46913 for fixed releases and apply the recommended updates to versions 9.2.0.0 through 9.2.26.2.

Workarounds

Enforce least privilege on the underlying operating system so only trusted administrators can log on to JD Edwards Tools hosts.
Segment JD Edwards EnterpriseOne Tools infrastructure from general-purpose servers and end-user workstations.
Disable unused local accounts and require multi-factor authentication for administrative access to the host platform.

bash

# Configuration example: restrict local logon on Linux hosts running JD Edwards Tools
# /etc/security/access.conf
