CVE-2026-47019: Oracle Product Hub Auth Bypass Flaw

CVE-2026-47019 Overview

CVE-2026-47019 is a high-severity vulnerability in the Item Catalog component of Oracle Product Hub, part of Oracle E-Business Suite. Affected releases span versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit the flaw to compromise Oracle Product Hub. Successful exploitation enables unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all Product Hub accessible data. Oracle disclosed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated attackers can read, modify, or delete any data accessible to Oracle Product Hub through network-based HTTP requests, breaking confidentiality and integrity of catalog and item master data.

Affected Products

Oracle E-Business Suite — Oracle Product Hub, version 12.2.3
Oracle E-Business Suite — Oracle Product Hub, versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Product Hub, version 12.2.15

Technical Details for CVE-2026-47019

Vulnerability Analysis

The flaw resides in the Item Catalog component of Oracle Product Hub, which manages item definitions, attributes, and catalog hierarchies within Oracle E-Business Suite. An attacker holding any low-privileged Product Hub account can reach the vulnerable functionality over the network using standard HTTP requests. No user interaction is required, and exploitation does not require adjacent network positioning.

Oracle rates the flaw with Confidentiality and Integrity impacts marked High, while Availability is unaffected. Successful exploitation grants the attacker the ability to read every record accessible to Product Hub and to create, modify, or delete those records. In practice, this can corrupt item master data, alter catalog attributes, or exfiltrate proprietary product definitions that feed downstream ERP and supply chain processes.

Root Cause

Oracle has not published root-cause details. The Critical Patch Update advisory attributes the issue to insufficient access enforcement within the Item Catalog component, allowing a session with minimal privileges to reach operations that should require higher authorization. Refer to the Oracle Security Alert July 2026 for the authoritative fix mapping.

Attack Vector

The attack vector is network-based over HTTP. An attacker authenticates to Oracle E-Business Suite with any low-privileged account, then issues crafted requests to Item Catalog endpoints. Because the exploit only requires an authenticated session and network reachability, any internally exposed Product Hub instance is at risk from insiders and any externally exposed instance is at risk from attackers who obtain low-tier credentials through phishing or credential reuse.

No verified public proof-of-concept code is available at the time of writing. The vulnerability should be treated as exploitable given the low attack complexity and privileges required.

Detection Methods for CVE-2026-47019

Indicators of Compromise

Unexpected create, update, or delete activity in MTL_SYSTEM_ITEMS_B, EGO_ITEM_*, and related Product Hub tables performed by low-privileged application users.
HTTP requests to Product Hub Item Catalog URLs originating from user accounts that historically only perform read operations.
Bulk item catalog exports or attribute changes outside of normal change-management windows.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking for Item Catalog pages and APIs.
Correlate application-tier access logs with database audit records for Product Hub schemas to identify privilege boundary crossings.
Baseline expected Item Catalog transaction volume per user role and alert on statistical deviations.

Monitoring Recommendations

Forward Oracle E-Business Suite application, middle-tier, and database audit logs into a centralized analytics platform for cross-source correlation.
Monitor authentication events for low-privileged Product Hub accounts, especially failed logins followed by successful ones from new source IPs.
Track outbound data volumes from the E-Business Suite application tier to detect bulk exfiltration of item master data.

How to Mitigate CVE-2026-47019

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running Product Hub versions 12.2.3 through 12.2.15.
Restrict network exposure of Oracle E-Business Suite to trusted networks and VPN users until patching is complete.
Review and reduce Product Hub role assignments, removing catalog access from users who do not require it.

Patch Information

Oracle released fixes for CVE-2026-47019 in the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2026 for exact patch identifiers, prerequisite bundles, and post-install steps for the E-Business Suite 12.2 code line.

Workarounds

If patching must be deferred, place Oracle E-Business Suite behind a web application firewall and restrict access to Item Catalog URLs to specific administrative source ranges.
Rotate credentials for low-privileged Product Hub accounts and enforce multi-factor authentication at the SSO or reverse-proxy layer.
Enable enhanced database auditing on Product Hub schemas so that any exploitation attempt produces investigable evidence.

bash

# Example: restrict Item Catalog paths at the reverse proxy until patching completes
# Apache httpd fragment
<LocationMatch "^/OA_HTML/.*(ItemCatalog|EGO).*">
    Require ip 10.10.0.0/16
    Require ip 10.20.5.0/24
