CVE-2026-46901: Oracle ECC Framework Auth Bypass Flaw

CVE-2026-46901 Overview

CVE-2026-46901 is a critical vulnerability in the Oracle Enterprise Command Center Framework, a component of Oracle E-Business Suite. The flaw exists in the Core component and affects supported versions V15 and V16. A low-privileged attacker with network access via HTTP can exploit this weakness with minimal complexity. Successful exploitation produces a scope change, meaning impact extends beyond the vulnerable component to additional Oracle products. Attackers gain unauthorized creation, deletion, and modification access to critical data, full read access to all framework-accessible data, and the ability to cause partial denial of service. The vulnerability is categorized under [CWE-269] Improper Privilege Management.

Critical Impact
An authenticated low-privileged attacker can compromise confidentiality and integrity across Oracle E-Business Suite components via a network-accessible HTTP request, with no user interaction required.

Affected Products

Oracle Enterprise Command Center Framework V15
Oracle Enterprise Command Center Framework V16
Oracle E-Business Suite deployments embedding the above versions

Technical Details for CVE-2026-46901

Vulnerability Analysis

The vulnerability resides in the Core component of the Oracle Enterprise Command Center Framework (ECC), the dashboard and analytics layer underpinning multiple Oracle E-Business Suite modules. An attacker authenticated with low privileges can issue crafted HTTP requests to the framework to escalate access. The exploit path requires no user interaction and carries low attack complexity. Because the vulnerability triggers a scope change, the compromise propagates from ECC into adjacent E-Business Suite components that trust ECC-mediated operations. Outcomes include unauthorized writes to critical data, complete read access to framework-accessible data, and partial denial of service against ECC services.

Root Cause

The weakness maps to [CWE-269] Improper Privilege Management. ECC fails to consistently enforce privilege boundaries on certain HTTP-accessible operations, allowing a low-privileged session to perform actions reserved for higher-trust roles. The scope change attribute indicates the trust boundary between ECC and downstream E-Business Suite components is not preserved during privilege evaluation.

Attack Vector

Exploitation occurs remotely over the network through the HTTP interface exposed by Oracle E-Business Suite. The attacker must hold valid low-privileged credentials but does not need administrative access. Once inside, the attacker submits HTTP requests to ECC endpoints that improperly evaluate authorization, then leverages the resulting elevated context to read or modify data across the integrated suite. Oracle has not published technical details of the exploitation flow. Refer to the Oracle Security Alert for vendor guidance.

Detection Methods for CVE-2026-46901

Indicators of Compromise

Unexpected HTTP requests to Oracle Enterprise Command Center Framework endpoints originating from low-privileged user sessions
Audit log entries showing data modification or deletion in E-Business Suite tables outside the user's normal role scope
Anomalous ECC dashboard queries returning data sets the requesting user is not authorized to view
Elevated error or timeout rates from ECC services indicating partial denial of service

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking, then alert on access to ECC pages by accounts not assigned ECC responsibilities
Correlate database audit trails (FND_LOGINS, FND_LOGIN_RESPONSIBILITIES) with HTTP access logs to identify privilege boundary violations
Baseline normal HTTP request patterns to ECC URLs and flag deviations in request volume, parameters, or response sizes

Monitoring Recommendations

Forward Oracle HTTP Server access logs and E-Business Suite concurrent manager logs to a centralized SIEM for retention and correlation
Monitor for repeated 4xx/5xx responses from ECC endpoints that may indicate enumeration or exploitation attempts
Track changes to sensitive E-Business Suite tables and reconcile against approved change tickets

How to Mitigate CVE-2026-46901

Immediate Actions Required

Apply the patches referenced in the Oracle June 2026 Critical Security Patch Update advisory to all ECC V15 and V16 instances
Inventory all Oracle E-Business Suite environments and confirm whether the Enterprise Command Center Framework is deployed and accessible
Restrict network access to ECC HTTP endpoints to trusted networks and authenticated users only
Review and tighten responsibility assignments so low-privileged accounts cannot reach ECC functions they do not need

Patch Information

Oracle addressed CVE-2026-46901 in the June 2026 Critical Security Patch Update. Customers must apply the fixes published in the Oracle Security Alert. Oracle's standard guidance is to apply CPU patches without delay, as Oracle does not provide additional details about specific security vulnerabilities beyond the advisory.

Workarounds

Place ECC behind a reverse proxy or web application firewall that enforces authentication and rate limits on framework URLs
Temporarily disable or restrict ECC dashboards in E-Business Suite for user populations that do not require them until patching is complete
Rotate credentials for any low-privileged accounts suspected of misuse and enforce multi-factor authentication on E-Business Suite logins

bash

# Example: restrict ECC endpoints at the Oracle HTTP Server level
# Add to httpd.conf or a virtual host include
<Location /OA_HTML/ecc>
    Order deny,allow
    Deny from all
    Allow from 10.0.0.0/8
    Allow from 192.168.0.0/16
