CVE-2026-46942: Oracle Process Manufacturing RCE Vulnerability

CVE-2026-46942 Overview

CVE-2026-46942 is a high-severity vulnerability in the Oracle Process Manufacturing Process Planning product, part of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this vulnerability to compromise the affected product. Successful exploitation results in full takeover of Oracle Process Manufacturing Process Planning, impacting confidentiality, integrity, and availability. The weakness is classified under CWE-269: Improper Privilege Management.

Critical Impact
An authenticated attacker with low privileges can take over Oracle Process Manufacturing Process Planning over the network, gaining full read, write, and availability impact on the product.

Technical Details for CVE-2026-46942

Vulnerability Analysis

The vulnerability exists in the Internal Operations component of Oracle Process Manufacturing Process Planning. The flaw allows an authenticated user holding only low-privileged credentials to escalate their access and compromise the entire product. Oracle classifies the issue as easily exploitable over HTTP without any user interaction. The scope remains unchanged, but confidentiality, integrity, and availability are all fully impacted, indicating an effective takeover of the affected module within Oracle E-Business Suite.

Root Cause

The underlying weakness maps to CWE-269: Improper Privilege Management. The Internal Operations component does not correctly enforce privilege boundaries between authenticated users. As a result, operations that should be restricted to higher-privileged roles are accessible to lower-privileged accounts, enabling lateral and vertical escalation inside the application.

Attack Vector

The attack vector is network-based. An attacker authenticates to the E-Business Suite environment with a low-privileged account and sends crafted HTTP requests to the Process Manufacturing Process Planning module. The request triggers privileged operations that the user should not be authorized to perform. Because authentication is required, this vulnerability is typically chained with credential theft, phishing, or insider access. The EPSS score of 0.447% reflects the lack of public proof-of-concept code at this time.

No verified public exploit code is available. Refer to the Oracle Critical Patch Update advisory for vendor technical details.

Detection Methods for CVE-2026-46942

Indicators of Compromise

Unexpected HTTP requests to Process Manufacturing Process Planning endpoints originating from low-privileged user sessions.
Audit log entries showing privileged operations executed by accounts without corresponding role assignments.
New or modified production plans, recipes, or internal operations records created outside normal change windows.
Authentication events from unusual source IPs followed by access to Internal Operations functionality.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to capture all access to Process Manufacturing Process Planning forms and pages.
Correlate FND_LOGINS and FND_USER tables against operations performed in Process Planning to identify privilege mismatches.
Deploy web application firewall rules that flag HTTP requests targeting Internal Operations endpoints from accounts that have not historically used them.

Monitoring Recommendations

Forward Oracle E-Business Suite application and database audit logs to a centralized SIEM for correlation with identity events.
Establish baselines for typical user behavior in Process Manufacturing modules and alert on deviations.
Monitor for changes to responsibilities, roles, and grants in FND_RESPONSIBILITY and FND_USER_RESP_GROUPS tables.

How to Mitigate CVE-2026-46942

Immediate Actions Required

Apply the Oracle Critical Patch Update referenced in the June 2026 Oracle Security Alert to all affected E-Business Suite environments.
Inventory all Oracle Process Manufacturing Process Planning deployments running versions 12.2.3 through 12.2.15 and prioritize internet-facing instances.
Review and reduce the number of accounts with access to Process Manufacturing responsibilities, enforcing least privilege.
Rotate credentials for accounts that have accessed the Internal Operations component during the exposure window.

Patch Information

Oracle addressed CVE-2026-46942 in the June 2026 Critical Patch Update. Customers should consult the Oracle Security Alert for the specific patch identifiers applicable to their Oracle E-Business Suite release. Apply patches in a test environment before production rollout, as Process Manufacturing patches frequently include database object updates.

Workarounds

Restrict network access to the Oracle E-Business Suite HTTP tier so that only trusted internal networks and VPN users can reach the Process Manufacturing Process Planning interface.
Temporarily revoke the Process Manufacturing Process Planning responsibility from non-essential users until patching is complete.
Enable strong multi-factor authentication for all E-Business Suite users to reduce the likelihood of credential abuse required for exploitation.

bash

# Example: restrict HTTP access to EBS Process Manufacturing endpoints at the reverse proxy
# Replace with your trusted CIDR ranges
location /OA_HTML/ {
    allow 10.0.0.0/8;
    allow 192.168.0.0/16;
    deny  all;
    proxy_pass http://ebs-internal-tier;
