CVE-2026-61274: Oracle Product Hub Auth Bypass Vulnerability

CVE-2026-61274 Overview

CVE-2026-61274 is an access control vulnerability [CWE-284] affecting the Item Catalog component of Oracle Product Hub within Oracle E-Business Suite. The flaw impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this vulnerability without user interaction. Successful exploitation allows unauthorized update, insert, or delete access to a subset of Oracle Product Hub data. Attackers can also gain unauthorized read access to a subset of data and cause a partial denial of service. Oracle addressed the issue in its July 2026 Critical Patch Update.

Critical Impact
Authenticated network-based attackers can modify, insert, delete, or read subsets of Oracle Product Hub data and trigger partial denial of service against the Item Catalog component.

Affected Products

Oracle E-Business Suite - Oracle Product Hub (Item Catalog component)
Supported versions 12.2.3 through 12.2.15
Deployments exposing Oracle Product Hub over HTTP to authenticated users

Technical Details for CVE-2026-61274

Vulnerability Analysis

The vulnerability resides in the Item Catalog component of Oracle Product Hub, part of Oracle E-Business Suite. It is classified under [CWE-284] Improper Access Control. An attacker with a valid low-privileged account can send crafted HTTP requests to the Product Hub interface. These requests bypass access control checks that should restrict data manipulation and retrieval. The scope remains unchanged, meaning exploitation affects only the vulnerable component. Confidentiality, integrity, and availability impacts are each partial rather than complete.

Root Cause

The root cause is improper enforcement of access controls on operations exposed by the Item Catalog module. Authorization logic fails to adequately verify that a low-privileged principal has rights to perform read, insert, update, or delete actions against certain catalog data. As a result, users authenticated with limited application roles can invoke functionality outside their intended privilege boundary.

Attack Vector

Exploitation requires network reachability to the Oracle Product Hub HTTP interface and valid low-privileged credentials. No user interaction is required. The attacker submits HTTP requests that target the Item Catalog endpoints and manipulate data or trigger resource conditions that cause partial denial of service. Because Oracle E-Business Suite deployments frequently expose HTTP interfaces internally to broad user populations, the low privilege requirement expands the pool of potential abusers to include standard business users.

No public proof-of-concept exploit is currently available. Consult the Oracle Critical Patch Update advisory for vendor-provided technical context.

Detection Methods for CVE-2026-61274

Indicators of Compromise

Unexpected create, update, or delete events against Item Catalog objects performed by low-privileged application accounts.
Anomalous HTTP request patterns targeting Oracle Product Hub Item Catalog endpoints from user sessions that historically only performed read activity.
Sudden spikes in Product Hub response latency or error rates indicative of a partial denial of service attempt.

Detection Strategies

Enable and review Oracle E-Business Suite audit trails for data changes on Item Catalog tables and correlate with the acting user's role assignments.
Baseline normal HTTP traffic to Product Hub endpoints and alert on deviations, including request volume spikes and unusual parameter values.
Correlate application-layer logs with database audit logs to identify actions that succeed at the application layer but violate role-based expectations.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web tier logs to a centralized SIEM for continuous review.
Monitor privileged and low-privileged user activity separately to identify lateral abuse of Item Catalog functionality.
Track the EPSS trend for CVE-2026-61274, currently 0.249% at the 16.34 percentile, and adjust monitoring priority if exploit likelihood increases.

How to Mitigate CVE-2026-61274

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite 12.2 environments running Oracle Product Hub.
Inventory all Product Hub deployments in versions 12.2.3 through 12.2.15 and prioritize internet-adjacent or broadly accessible instances.
Review and tighten role assignments so that only required users hold Product Hub responsibilities.

Patch Information

Oracle released fixes for CVE-2026-61274 as part of the July 2026 Critical Patch Update. Administrators should follow Oracle's documented patch application procedures for E-Business Suite 12.2 and validate patch installation across application, database, and middle tiers. Refer to the Oracle Critical Patch Update for full patch identifiers and installation notes.

Workarounds

Restrict network access to Oracle Product Hub HTTP endpoints using firewall rules, reverse proxy allowlists, or VPN gating until patches are deployed.
Reduce the count of low-privileged accounts that can reach Item Catalog functionality and enforce least privilege on Product Hub responsibilities.
Increase logging verbosity on Product Hub and its supporting database schemas to accelerate identification of abuse attempts.

bash

# Example: restrict Product Hub HTTP access at the network layer
# Replace 10.0.0.0/24 with your trusted admin subnet
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
