CVE-2026-61039: Oracle Advanced Supply Chain Escalation

CVE-2026-61039 Overview

CVE-2026-61039 is a high-severity vulnerability in the Oracle Advanced Supply Chain Planning product, part of the Oracle E-Business Suite (component: Core). Supported versions 12.2.3 through 12.2.15 are affected. A high-privileged attacker with network access via HTTP can exploit this flaw to compromise Oracle Advanced Supply Chain Planning. Successful exploitation results in full takeover of the application, impacting confidentiality, integrity, and availability. Oracle disclosed the issue in the Oracle Security Alert July 2026.

Critical Impact
Successful exploitation grants complete takeover of Oracle Advanced Supply Chain Planning, exposing supply chain data and business processes to compromise.

Technical Details for CVE-2026-61039

Vulnerability Analysis

The vulnerability resides in the Core component of Oracle Advanced Supply Chain Planning within Oracle E-Business Suite. Oracle characterizes the flaw as easily exploitable over HTTP by an authenticated attacker holding high privileges. Successful exploitation compromises confidentiality, integrity, and availability, allowing complete takeover of the Advanced Supply Chain Planning module.

Because the module orchestrates demand planning, inventory positioning, and production scheduling, an attacker gaining control can manipulate business-critical supply chain data. The scope is unchanged, meaning the compromise is contained within the vulnerable component, but the impact within that boundary is total.

Root Cause

Oracle has not published root cause details in the public advisory. The Oracle Security Alert July 2026 confirms the flaw exists in the Core component and requires high privileges combined with network access via HTTP. No CWE identifier has been assigned in the NVD entry.

Attack Vector

The attack vector is Network (HTTP). The attacker must already hold high privileges within the Oracle E-Business Suite environment, and no user interaction is required. An authenticated administrator or a compromised privileged account can send crafted HTTP requests to the Advanced Supply Chain Planning endpoints and take control of the application.

Exploitation code is not publicly available at the time of publication. The EPSS probability is 0.465% (percentile 37.698) as of 2026-07-23, indicating a low but non-zero near-term exploitation likelihood.

No verified proof-of-concept has been released. Refer to the Oracle Security Alert July 2026 for authoritative technical guidance.

Detection Methods for CVE-2026-61039

Indicators of Compromise

Unexpected HTTP requests to Oracle Advanced Supply Chain Planning URLs originating from privileged accounts outside normal administrative windows.
Modifications to supply chain planning configuration, schedules, or master data without a corresponding change ticket.
New or altered database objects, concurrent programs, or scheduled jobs within the MSC (Manufacturing Supply Chain) schema.

Detection Strategies

Enable Oracle E-Business Suite audit logging for privileged users and forward records to a central SIEM for correlation.
Alert on anomalous session activity from SYSADMIN or supply chain planner roles, particularly outside expected working hours.
Monitor web tier access logs for requests targeting Advanced Supply Chain Planning servlets and JSPs that deviate from baseline patterns.

Monitoring Recommendations

Baseline HTTP request patterns to the Oracle E-Business Suite application tier and alert on statistically significant deviations.
Track privileged role assignments and responsibilities in FND tables (FND_USER, FND_USER_RESP_GROUPS) for unauthorized changes.
Integrate database audit trails with endpoint and identity telemetry to reconstruct the full session activity of privileged users.

How to Mitigate CVE-2026-61039

Immediate Actions Required

Apply the July 2026 Critical Patch Update from Oracle to all Oracle E-Business Suite deployments running affected versions of Advanced Supply Chain Planning.
Inventory all instances running versions 12.2.3 through 12.2.15 and prioritize internet-adjacent and business-critical systems.
Rotate credentials for privileged Oracle E-Business Suite accounts and review responsibility assignments granting access to Advanced Supply Chain Planning.

Patch Information

Oracle addresses CVE-2026-61039 in the Oracle Security Alert July 2026. Administrators should follow the Critical Patch Update advisory and apply the patches referenced for the Advanced Supply Chain Planning product line in Oracle E-Business Suite 12.2.x.

Workarounds

Restrict network access to the Oracle E-Business Suite application tier to trusted internal networks and jump hosts until patches are applied.
Enforce multi-factor authentication and strict least-privilege on all administrative and planner accounts to limit the pool of accounts meeting the high-privilege exploitation prerequisite.
Increase logging verbosity on the application and database tiers to shorten identification time if exploitation is attempted before patching completes.

bash

# Example: restrict access to the E-Business Suite application tier at the network layer
# Replace 10.0.0.0/24 with your trusted administrative subnet
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
