CVE-2026-61050: Oracle Production Scheduling Data Disclosure

CVE-2026-61050 Overview

CVE-2026-61050 affects the Oracle Production Scheduling product within Oracle E-Business Suite, specifically the User Interface component. Supported versions 12.2.3 through 12.2.15 are affected. A low-privileged attacker with network access via HTTP can exploit the flaw, though successful exploitation is difficult. The vulnerability impacts confidentiality only, potentially allowing unauthorized access to all Oracle Production Scheduling accessible data.

Oracle disclosed the issue in the Critical Patch Update of July 2026. No public exploit is known, and the flaw is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog.

Critical Impact
Successful exploitation can result in unauthorized read access to all data accessible by Oracle Production Scheduling, including business-critical scheduling and manufacturing records.

Affected Products

Oracle E-Business Suite — Oracle Production Scheduling 12.2.3 through 12.2.15
Component: User Interface
Deployment: Network-accessible HTTP endpoints of Oracle Production Scheduling

Technical Details for CVE-2026-61050

Vulnerability Analysis

The flaw resides in the User Interface component of Oracle Production Scheduling, part of the Oracle E-Business Suite. Because the attack vector is network-based over HTTP, an authenticated user with low privileges can attempt to exploit the weakness remotely. Attack complexity is high, meaning exploitation requires specific conditions outside the attacker's direct control. Successful exploitation compromises confidentiality only, with no impact on integrity or availability. The EPSS probability sits at 0.284%, indicating a low near-term exploitation likelihood, and no proof-of-concept has been released publicly.

Root Cause

Oracle has not published detailed root-cause information. The advisory categorizes the issue as an information disclosure flaw within the User Interface component. Based on the CVSS metrics, the weakness enables an authenticated actor to obtain data that should be restricted by application access controls. See the Oracle Critical Patch Update July 2026 for vendor-supplied technical details.

Attack Vector

An attacker must hold valid low-privileged credentials for the Oracle Production Scheduling application. The attacker then sends crafted HTTP requests to the vulnerable User Interface endpoint. Because the scope is unchanged and only confidentiality is affected, the attacker can read data within Oracle Production Scheduling but cannot modify records or disrupt service through this vulnerability alone.

No verified exploit code is available. Refer to Oracle's advisory for authoritative guidance.

Detection Methods for CVE-2026-61050

Indicators of Compromise

Unusual volumes of authenticated HTTP requests to Oracle Production Scheduling User Interface endpoints from a single low-privileged account.
Application or middleware log entries showing repeated access to scheduling data outside a user's normal role.
Access patterns originating from IP addresses not previously associated with the authenticated user.

Detection Strategies

Enable Oracle E-Business Suite audit logging for Production Scheduling modules and forward logs to a centralized SIEM.
Correlate authentication events with data access events to flag privilege boundaries being crossed at the application layer.
Baseline normal Production Scheduling API and UI request patterns per user role, then alert on statistical outliers.

Monitoring Recommendations

Monitor Oracle HTTP Server (OHS) access logs for anomalous URL patterns targeting Production Scheduling endpoints.
Track failed and successful logins to low-privileged Oracle E-Business Suite accounts, especially from new geolocations.
Alert on database queries returning large result sets from Production Scheduling tables initiated by non-administrative accounts.

How to Mitigate CVE-2026-61050

Immediate Actions Required

Apply the fixes provided in the Oracle Critical Patch Update July 2026 to all affected Oracle E-Business Suite installations.
Inventory Oracle Production Scheduling instances running versions 12.2.3 through 12.2.15 and prioritize internet-facing systems.
Rotate credentials for low-privileged accounts that could be leveraged against exposed Production Scheduling endpoints.
Restrict HTTP access to Oracle E-Business Suite User Interface endpoints to trusted networks or VPN users.

Patch Information

Oracle addressed CVE-2026-61050 in the July 2026 Critical Patch Update. Administrators should download and apply the relevant patch bundle for their Oracle E-Business Suite 12.2.x release. Follow Oracle's standard patch verification procedure, including post-install validation of the Production Scheduling module. Consult the Oracle Critical Patch Update July 2026 advisory for patch identifiers and prerequisite bundles.

Workarounds

Place Oracle E-Business Suite behind a reverse proxy or web application firewall (WAF) that enforces role-based URL restrictions.
Temporarily disable or restrict the Production Scheduling User Interface for accounts that do not require it until patching is complete.
Enforce multi-factor authentication (MFA) on all Oracle E-Business Suite user accounts to reduce the risk of low-privileged credential abuse.

bash

# Example: restrict access to Oracle Production Scheduling UI paths at the reverse proxy layer
# (Adjust paths and IP ranges to match your environment)
location /OA_HTML/ {
    allow 10.0.0.0/8;      # internal corporate range
    allow 192.168.10.0/24; # jump-host subnet
    deny  all;
    proxy_pass https://ebs-backend.internal;
