CVE-2026-61310: Oracle Product Hub Auth Bypass Flaw

CVE-2026-61310 Overview

CVE-2026-61310 affects the Oracle Product Hub component of Oracle E-Business Suite, specifically the Internal Operations module. The vulnerability allows a low-privileged attacker with network access via HTTP to compromise Oracle Product Hub. Successful exploitation results in unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all Oracle Product Hub accessible data. Oracle disclosed the flaw in the July 2026 Critical Patch Update. The weakness is classified under [CWE-284] Improper Access Control.

Critical Impact
Authenticated attackers can read, modify, or delete critical business data across Oracle Product Hub over the network with low attack complexity.

Affected Products

Oracle E-Business Suite - Oracle Product Hub
Supported versions 12.2.3 through 12.2.15

Technical Details for CVE-2026-61310

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Product Hub, part of Oracle E-Business Suite. An attacker with a valid low-privileged account can send crafted HTTP requests that bypass intended access restrictions. The flaw does not require user interaction and can be exploited remotely over the network. Successful exploitation compromises both the confidentiality and integrity of data managed by Product Hub. Availability is not directly affected according to the CVSS vector published by Oracle.

Root Cause

The root cause is improper access control [CWE-284] within the Internal Operations component. Server-side authorization checks fail to properly restrict actions available to low-privileged authenticated users. As a result, the application honors requests that should be reserved for higher-privileged roles. This design gap enables horizontal and vertical access to product master data, item catalogs, and related operational records.

Attack Vector

The attack vector is network-based over HTTP. The attacker must hold a valid low-privileged Oracle E-Business Suite account, which is common in large deployments with many internal users, suppliers, and partners. After authentication, the attacker issues crafted HTTP requests to Product Hub endpoints exposed by the Internal Operations component. No user interaction is required, and the scope remains unchanged. The impacted data includes item definitions, product structures, and related business-critical records.

Oracle has not publicly released technical exploitation details. See the Oracle Critical Patch Update July 2026 advisory for vendor guidance.

Detection Methods for CVE-2026-61310

Indicators of Compromise

Unexpected creation, modification, or deletion of Product Hub items, catalogs, or attributes by low-privileged accounts.
HTTP requests targeting Internal Operations endpoints from user accounts that do not typically perform administrative actions.
Audit log entries showing privilege-sensitive operations executed by users lacking corresponding roles.
Spikes in API calls to Product Hub interfaces outside of scheduled batch or integration windows.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and page access tracking for Product Hub responsibilities.
Correlate web tier access logs with application-level audit trails to identify unauthorized data changes.
Baseline normal Product Hub usage per role and alert on deviations, particularly write operations from read-only users.
Deploy database-level auditing on EGO_* and MTL_* tables to capture item and catalog changes with user attribution.

Monitoring Recommendations

Forward Oracle E-Business Suite application, web tier, and database audit logs to a centralized SIEM for correlation.
Monitor authentication events for the accounts most likely to be targeted, including service accounts and shared users.
Track patch state of all Oracle E-Business Suite environments and flag hosts still running versions 12.2.3 through 12.2.15 without the July 2026 CPU applied.

How to Mitigate CVE-2026-61310

Immediate Actions Required

Apply the Oracle Critical Patch Update July 2026 to all Oracle E-Business Suite environments running Product Hub versions 12.2.3 through 12.2.15.
Inventory all users with any Product Hub responsibility and remove entitlements that are not strictly required.
Restrict network access to Oracle E-Business Suite HTTP endpoints so only trusted internal networks and VPN clients can reach them.
Rotate credentials for any account suspected of misuse and review audit logs for unauthorized changes prior to patching.

Patch Information

Oracle addressed CVE-2026-61310 in the July 2026 Critical Patch Update. Refer to the Oracle Critical Patch Update July 2026 advisory for patch numbers, prerequisites, and installation guidance specific to your Oracle E-Business Suite release. Apply the patch in a test environment first, validate integrations, then promote to production following standard change control.

Workarounds

No official vendor workaround exists. Apply the July 2026 CPU as the primary remediation.
Reduce exposure by placing Oracle E-Business Suite behind a reverse proxy or web application firewall that enforces strict authentication and rate limiting.
Temporarily revoke Product Hub responsibilities from non-essential users until patching completes.
Enable enhanced auditing on Product Hub tables to increase visibility during the interim period.
