CVE-2026-61311: Oracle Product Hub Privilege Escalation

CVE-2026-61311 Overview

CVE-2026-61311 is a high-severity vulnerability in the Oracle Product Hub component of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this vulnerability to compromise Oracle Product Hub. Successful exploitation results in complete takeover of the application, impacting confidentiality, integrity, and availability. The vulnerability is categorized under [CWE-269] Improper Privilege Management.

Critical Impact
Successful attacks result in full takeover of Oracle Product Hub, exposing sensitive product master data and enabling unauthorized modification of enterprise business records.

Technical Details for CVE-2026-61311

Vulnerability Analysis

The vulnerability exists within the Internal Operations component of Oracle Product Hub, a master data management application inside Oracle E-Business Suite. An authenticated attacker holding a low-privileged account can send crafted HTTP requests to the affected functionality and elevate access to fully compromise the Product Hub instance. The attack requires no user interaction and operates over the network, making it viable from any endpoint that can reach the application tier. Successful exploitation compromises product master data, supplier relationships, and downstream business processes that depend on Product Hub data.

Root Cause

The underlying weakness maps to [CWE-269] Improper Privilege Management. The Internal Operations component fails to correctly enforce privilege boundaries when handling requests from authenticated sessions. Actions or resources that should be restricted to higher-privileged roles remain reachable by low-privileged users, allowing horizontal and vertical privilege escalation within the Product Hub application context.

Attack Vector

Exploitation occurs remotely over HTTP against the Oracle E-Business Suite application tier. The attacker must first authenticate with a low-privileged account, which is common in large ERP deployments where hundreds or thousands of employee accounts exist. Once authenticated, the attacker issues crafted requests to the vulnerable Internal Operations endpoints. Because attack complexity is low and no user interaction is required, an attacker with valid credentials can reliably escalate to full application takeover. No public proof-of-concept exploit code has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS probability is 0.447% as of 2026-07-22.

No verified proof-of-concept code is available. Refer to the Oracle Security Alert July 2026 for authoritative technical details.

Detection Methods for CVE-2026-61311

Indicators of Compromise

Unexpected privilege changes or role assignments within Oracle Product Hub audit tables such as FND_USER and WF_LOCAL_USER_ROLES.
Anomalous HTTP requests to Internal Operations URLs originating from low-privileged user sessions.
Modifications to product master data, item catalogs, or supplier records performed outside of standard change windows by non-administrative accounts.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to identify low-privileged users accessing Internal Operations pages.
Correlate application-tier access logs with database audit trails to detect privilege escalation patterns.
Establish a baseline of expected Product Hub API and page access per role, then alert on deviations.

Monitoring Recommendations

Forward Oracle E-Business Suite application, middle-tier, and database audit logs to a centralized SIEM for continuous analysis.
Alert on repeated HTTP 4xx and 5xx responses against Product Hub endpoints, which may indicate exploitation attempts.
Monitor for creation of new administrative roles or responsibilities assigned to previously low-privileged accounts.

How to Mitigate CVE-2026-61311

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running Product Hub 12.2.3 through 12.2.15.
Audit existing user accounts and remove or disable unused low-privileged accounts that could serve as an exploitation foothold.
Restrict network access to the Oracle E-Business Suite application tier so that only trusted internal networks and authorized users can reach HTTP endpoints.

Patch Information

Oracle addressed this vulnerability in the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2026 for patch identifiers, prerequisites, and installation instructions specific to Oracle E-Business Suite 12.2.x releases. Apply the patch in a test environment before promoting to production.

Workarounds

Enforce least-privilege principles by reviewing Product Hub responsibilities and removing unnecessary access from standard user roles.
Place the Oracle E-Business Suite application tier behind a web application firewall configured to inspect and rate-limit requests to Internal Operations endpoints.
Require multi-factor authentication for all Oracle E-Business Suite accounts to reduce the risk of credential compromise leading to exploitation.
