CVE-2026-70760: Oracle Order Management Auth Bypass Flaw

CVE-2026-70760 Overview

CVE-2026-70760 affects the Product Diagnostic Tools component of Oracle Order Management, part of Oracle E-Business Suite. Supported versions 12.2.3 through 12.2.15 are affected. A low-privileged attacker with network access via HTTP can compromise Oracle Order Management, though exploitation is difficult. Because the vulnerability produces a scope change, successful attacks can significantly affect additional products beyond Order Management itself. Impact includes unauthorized access to critical data and unauthorized update, insert, or delete access to a subset of Oracle Order Management data.

Critical Impact
Successful exploitation enables cross-product data disclosure and partial data modification across resources reachable from Oracle Order Management.

Affected Products

Oracle E-Business Suite — Oracle Order Management 12.2.3
Oracle E-Business Suite — Oracle Order Management versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Order Management 12.2.15

Technical Details for CVE-2026-70760

Vulnerability Analysis

The vulnerability resides in the Product Diagnostic Tools component of Oracle Order Management. An authenticated attacker holding low privileges can send crafted HTTP requests to interact with the affected diagnostic functionality. Exploitation requires overcoming conditions outside the attacker's control, which raises attack complexity. Once exploited, the flaw crosses a trust boundary and affects resources managed by other components. That scope change permits disclosure of critical data along with limited modification of data accessible through Oracle Order Management. Oracle categorizes the impact as high to confidentiality and low to integrity, with no availability impact.

Root Cause

Oracle has not published a detailed root-cause analysis. The advisory identifies the Product Diagnostic Tools component as the affected code path and confirms that exploitation traverses component boundaries within the E-Business Suite deployment. The scope change indicates that the vulnerable code operates with authority extending beyond Oracle Order Management's own security domain.

Attack Vector

Exploitation is remote over HTTP against an internet-reachable or intranet-reachable Oracle E-Business Suite instance. The attacker must first authenticate with a low-privileged account. No user interaction is required. Attack complexity is high, meaning the attacker must satisfy specific runtime conditions before a request succeeds. Consult the Oracle Security Alert for vendor-supplied technical guidance.

Detection Methods for CVE-2026-70760

Indicators of Compromise

Unexpected HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Product Diagnostic Tools endpoints within Oracle Order Management.
Access to Order Management data records by user sessions that historically have no business need to query them.
Cross-module data reads or writes originating from Order Management sessions where the target data belongs to other E-Business Suite products.

Detection Strategies

Enable and review Oracle E-Business Suite audit logs, focusing on authenticated sessions that interact with Product Diagnostic Tools URLs.
Correlate HTTP access logs from Oracle HTTP Server with application-tier audit records to identify anomalous request patterns from low-privileged users.
Baseline normal Order Management usage per role and alert on deviations that indicate scope-crossing data access.

Monitoring Recommendations

Ingest Oracle E-Business Suite web-tier and application-tier logs into a centralized SIEM for retention and correlation.
Monitor privileged data tables reachable through Order Management for unexpected SELECT, INSERT, UPDATE, or DELETE activity attributable to low-privileged sessions.
Alert on authentication anomalies for E-Business Suite accounts, including new source IP addresses and off-hours activity.

How to Mitigate CVE-2026-70760

Immediate Actions Required

Apply the Oracle patch published in the August 2026 Critical Patch Update Advisory for E-Business Suite 12.2.3 through 12.2.15.
Inventory all Oracle E-Business Suite deployments and confirm the running Order Management version against the affected range.
Restrict network exposure of Oracle E-Business Suite web endpoints to trusted networks and VPN users only.
Review and prune E-Business Suite user accounts, revoking low-privileged accounts that are no longer required.

Patch Information

Oracle addressed CVE-2026-70760 in the August 2026 security update. Refer to the Oracle Security Alert for the applicable patch identifiers and installation prerequisites for each supported 12.2.x release.

Workarounds

Limit access to Product Diagnostic Tools functionality by adjusting E-Business Suite responsibilities and menu exclusions where operationally feasible.
Place a web application firewall in front of the Oracle E-Business Suite web tier to filter unexpected requests to diagnostic URLs.
Enforce multi-factor authentication on all E-Business Suite accounts to raise the cost of low-privileged account compromise.
