CVE-2026-70774 Overview
CVE-2026-70774 affects the Oracle Warehouse Management product within Oracle E-Business Suite, specifically the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are affected. A low-privileged attacker with network access via HTTP can exploit this flaw to compromise integrity and cause partial denial of service against Oracle Warehouse Management. The weakness is classified under CWE-284: Improper Access Control. Successful exploitation grants unauthorized create, delete, or modify access to critical Oracle Warehouse Management data.
Critical Impact
An authenticated attacker over the network can modify or delete all Oracle Warehouse Management accessible data and induce a partial denial of service against the application.
Affected Products
- Oracle E-Business Suite — Oracle Warehouse Management 12.2.3
- Oracle E-Business Suite — Oracle Warehouse Management versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle Warehouse Management 12.2.15

Technical Details for CVE-2026-70774
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle Warehouse Management, part of the broader Oracle E-Business Suite. An attacker requires only low privileges and network reachability to the application over HTTP. No user interaction is needed, and attack complexity is low.
Successful exploitation allows unauthorized creation, deletion, or modification of records across the full set of Oracle Warehouse Management accessible data. It also enables a partial denial of service against the application, disrupting warehouse operations that depend on the module.
The root weakness maps to CWE-284: Improper Access Control, indicating that the affected code path does not correctly enforce authorization on requests that reach the Internal Operations component.
Root Cause
Oracle has not published implementation-level details. Based on the CWE-284 classification, the flaw stems from missing or insufficient authorization checks that permit an authenticated user with minimal privileges to invoke operations that should be restricted to higher-privileged roles.
Attack Vector
Exploitation occurs over the network via HTTP against the Oracle Warehouse Management application. The attacker must hold a valid low-privilege account. Once authenticated, the attacker sends crafted requests to the vulnerable Internal Operations endpoint to alter or destroy data, or to trigger conditions that degrade application availability.
No verified proof-of-concept code is publicly available. Refer to the Oracle Security Alert for vendor-supplied technical context.
Detection Methods for CVE-2026-70774
Indicators of Compromise
- Unexpected create, update, or delete operations against Oracle Warehouse Management records performed by low-privileged accounts.
- HTTP requests to Internal Operations endpoints originating from user sessions that historically do not access those functions.
- Sudden bursts of failed or malformed requests correlating with partial service outages in the Warehouse Management module.
Detection Strategies
- Audit Oracle E-Business Suite application logs for authorization anomalies tied to the Internal Operations component.
- Correlate database audit records with application-level user sessions to identify data modifications that bypass expected role restrictions.
- Baseline normal HTTP traffic to the Warehouse Management module and alert on deviations in request volume, endpoints, or user-agent patterns.
Monitoring Recommendations
- Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking for the Warehouse Management responsibility.
- Forward web tier and database audit logs to a centralized analytics platform for retention and correlation.
- Alert on privileged data operations executed by accounts that lack corresponding Oracle responsibilities.
How to Mitigate CVE-2026-70774
Immediate Actions Required
- Apply the fixes referenced in the Oracle Critical Patch Update Security Alert (August 2026) to all affected Oracle E-Business Suite deployments.
- Inventory Oracle Warehouse Management instances running versions 12.2.3 through 12.2.15 and prioritize patching based on internet exposure.
- Review and tighten role assignments for the Warehouse Management module to enforce least privilege.
Patch Information
Oracle has published fixes as part of its scheduled security update cycle. Consult the Oracle Security Alert for the specific patch identifiers, prerequisites, and application instructions for Oracle E-Business Suite 12.2.x.
Workarounds
- Restrict network access to Oracle E-Business Suite web tiers so that only trusted internal networks and VPN users can reach the application.
- Remove or restrict Warehouse Management responsibilities from user accounts that do not require Internal Operations access.
- Increase audit granularity on Warehouse Management tables until patching is complete to shorten the window for detecting unauthorized changes.
