CVE-2026-61046: Oracle Production Scheduling Escalation Flaw

CVE-2026-61046 Overview

CVE-2026-61046 is a vulnerability in the Oracle Production Scheduling product within Oracle E-Business Suite, specifically in the Internal Operations component. Affected releases span versions 12.2.3 through 12.2.15. An attacker with high privileges and network access via HTTP can compromise Oracle Production Scheduling, and successful exploitation can affect additional products due to a scope change. Impact includes unauthorized creation, deletion, or modification of critical data, plus unauthorized read access to a subset of Production Scheduling data. Oracle disclosed the issue in the Oracle July 2026 Security Alert.

Critical Impact
Authenticated attackers can modify or destroy critical scheduling data and impact adjacent Oracle E-Business Suite components through scope change.

Affected Products

Oracle E-Business Suite - Oracle Production Scheduling 12.2.3
Oracle E-Business Suite - Oracle Production Scheduling 12.2.15
All intermediate versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-61046

Vulnerability Analysis

The flaw resides in the Internal Operations component of Oracle Production Scheduling, a module of Oracle E-Business Suite responsible for planning and sequencing manufacturing tasks. Oracle classifies the issue as difficult to exploit and requires an attacker who already holds high privileges on the target environment. Despite these prerequisites, exploitation produces a scope change, meaning consequences extend beyond Production Scheduling itself into other components sharing trust with the module.

The primary security impact is on data integrity. A successful attacker can create, delete, or modify critical scheduling records, disrupting production planning workflows and downstream ERP processes. A secondary confidentiality impact allows read access to a subset of Production Scheduling data. Availability is not directly affected.

Root Cause

Oracle has not published root-cause details. The advisory attributes the issue to the Internal Operations component of Production Scheduling and indicates the trust boundary between this component and adjacent products is insufficient, enabling the scope change described in the CVSS vector.

Attack Vector

Exploitation requires authenticated HTTP access to the Production Scheduling application. The attacker must possess high-privilege credentials, which limits the pool of eligible actors to insiders, compromised administrative accounts, or attackers who have chained a prior privilege escalation. No user interaction is required. Technical details of the exploitation path are not publicly available; refer to the Oracle July 2026 Security Alert for vendor guidance.

Detection Methods for CVE-2026-61046

Indicators of Compromise

Unexpected creation, deletion, or modification of Production Scheduling records outside normal change windows or by unusual accounts.
Anomalous HTTP requests to Production Scheduling endpoints originating from administrative accounts operating outside their normal usage patterns.
Cross-module data changes in Oracle E-Business Suite that correlate with Production Scheduling activity, consistent with the CVSS scope change.

Detection Strategies

Enable Oracle E-Business Suite auditing on Production Scheduling tables and log all data manipulation statements executed under privileged accounts.
Baseline normal administrative HTTP traffic to Production Scheduling and alert on deviations in request volume, method, or endpoint diversity.
Correlate authentication events for privileged accounts with subsequent write operations against Internal Operations objects.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web-tier logs to a centralized analytics platform for retention and correlation.
Monitor for privileged session activity outside change windows and require ticket correlation for administrative actions.
Review Oracle Critical Patch Update compliance status across all E-Business Suite environments on a recurring cadence.

How to Mitigate CVE-2026-61046

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running Production Scheduling versions 12.2.3 through 12.2.15.
Inventory accounts with high privileges on Production Scheduling and validate that each account is still required and appropriately scoped.
Rotate credentials for privileged Production Scheduling accounts and enforce multi-factor authentication where supported.

Patch Information

Oracle addressed CVE-2026-61046 in the July 2026 Critical Patch Update. Administrators should follow the patch instructions in the Oracle July 2026 Security Alert and validate patch application in non-production environments before rolling out to production.

Workarounds

Restrict HTTP access to Production Scheduling endpoints to authorized administrative networks using network segmentation and firewall rules.
Reduce the number of accounts with high privileges on Production Scheduling to the minimum required for operations.
Increase audit logging verbosity on the Internal Operations component and review logs frequently until the patch is deployed.

bash

# Configuration example: restrict network access to Production Scheduling web tier
# Replace <admin_subnet> and <ebs_web_host> with environment-specific values
iptables -A INPUT -p tcp --dport 8000 -s <admin_subnet> -d <ebs_web_host> -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -d <ebs_web_host> -j DROP
