CVE-2026-70771: Oracle Warehouse Management Info Leak Flaw

CVE-2026-70771 Overview

CVE-2026-70771 is a vulnerability in the Oracle Warehouse Management product of Oracle E-Business Suite, specifically within the Internal Operations component. Supported versions 12.2.3 through 12.2.15 are affected. The flaw allows a low-privileged attacker with network access via HTTPS to compromise Oracle Warehouse Management. Successful exploitation can result in unauthorized access to critical data or complete access to all Oracle Warehouse Management accessible data. The vulnerability carries a scope change, meaning attacks may significantly impact additional Oracle products beyond Warehouse Management itself.

Critical Impact
A low-privileged authenticated attacker can access all data within Oracle Warehouse Management and affect additional Oracle products through the scope change.

Affected Products

Oracle E-Business Suite - Oracle Warehouse Management 12.2.3
Oracle E-Business Suite - Oracle Warehouse Management 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle Warehouse Management 12.2.15

Technical Details for CVE-2026-70771

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Warehouse Management, part of the Oracle E-Business Suite platform. Oracle classifies exploitation as easy, requiring only network access over HTTPS and low authenticated privileges. No user interaction is required to trigger the flaw. Impact is limited to confidentiality; integrity and availability are not affected. The scope change indicates the vulnerable component can influence resources beyond its own security authority, extending the blast radius to related Oracle E-Business Suite products.

Root Cause

Oracle has not published detailed technical root-cause information for CVE-2026-70771. The advisory characterizes the issue as an authenticated data exposure flaw in the Internal Operations component. Refer to the Oracle Security Alert for authoritative vendor guidance.

Attack Vector

Exploitation requires network reachability to the Oracle Warehouse Management HTTPS endpoint and a valid low-privileged account within the E-Business Suite environment. Once authenticated, the attacker sends crafted requests to the Internal Operations component to retrieve data outside the intended authorization boundary. Because the scope changes during exploitation, data belonging to other Oracle products in the same deployment may also be exposed. No verified public exploit code is available at this time, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS probability is 0.371% as of 2026-08-20.

Detection Methods for CVE-2026-70771

Indicators of Compromise

Unusual HTTPS request patterns to Oracle Warehouse Management Internal Operations endpoints originating from low-privileged user sessions.
Anomalous volumes of data returned to authenticated Warehouse Management users, especially outside normal business hours.
Access attempts from Warehouse Management sessions targeting data owned by adjacent Oracle E-Business Suite modules.

Detection Strategies

Enable and review Oracle E-Business Suite application audit logs for the Internal Operations component, focusing on read operations against sensitive tables.
Baseline typical query volume per user role and alert on deviations that suggest bulk data extraction.
Correlate web tier HTTPS logs with application-layer audit events to identify authenticated abuse.

Monitoring Recommendations

Forward Oracle E-Business Suite audit trails and Oracle HTTP Server logs to a centralized analytics platform for retention and correlation.
Monitor low-privileged accounts for privilege boundary violations and unexpected access to Warehouse Management data.
Alert on repeated failed and successful authentication events from the same source targeting Warehouse Management URLs.

How to Mitigate CVE-2026-70771

Immediate Actions Required

Apply the fixes referenced in the Oracle Security Alert to all Oracle E-Business Suite deployments running versions 12.2.3 through 12.2.15.
Inventory all E-Business Suite instances and confirm the Oracle Warehouse Management module status and version.
Rotate credentials for any low-privileged accounts that could reach the Internal Operations component if compromise is suspected.

Patch Information

Oracle addressed CVE-2026-70771 in its August 2026 security alert bundle. Consult the Oracle Security Alert for the specific patch identifiers applicable to each supported version between 12.2.3 and 12.2.15. Apply the patches through the standard Oracle E-Business Suite patching process and validate application functionality afterward.

Workarounds

Restrict network access to Oracle Warehouse Management HTTPS endpoints to trusted internal networks and VPN users only.
Enforce least privilege for E-Business Suite responsibilities and remove Warehouse Management access from users who do not require it.
Enable Oracle E-Business Suite auditing on the Internal Operations component to detect exploitation attempts until patches are deployed.

bash

# Configuration example
# Restrict inbound HTTPS access to Oracle E-Business Suite web tier
# Example iptables rule allowing only trusted subnet
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/16 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
