CVE-2026-62513: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-62513 Overview

CVE-2026-62513 is a high-severity access control vulnerability [CWE-284] affecting the Oracle Process Manufacturing Regulatory Management product within Oracle E-Business Suite. The flaw resides in the Internal Operations component and impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this vulnerability without user interaction. Successful exploitation leads to unauthorized access to critical data across the module, along with limited unauthorized update, insert, or delete access. The vulnerability triggers a scope change, meaning exploitation can affect resources beyond the vulnerable component itself.

Critical Impact
Low-privileged network attackers can compromise Oracle Process Manufacturing Regulatory Management, gain complete read access to sensitive regulatory data, and modify records across multiple integrated Oracle E-Business Suite products.

Affected Products

Oracle E-Business Suite - Oracle Process Manufacturing Regulatory Management 12.2.3
Oracle E-Business Suite - Oracle Process Manufacturing Regulatory Management versions 12.2.4 through 12.2.14
Oracle E-Business Suite - Oracle Process Manufacturing Regulatory Management 12.2.15

Technical Details for CVE-2026-62513

Vulnerability Analysis

The vulnerability originates in the Internal Operations component of Oracle Process Manufacturing Regulatory Management. The module fails to enforce proper access control checks on requests submitted by authenticated users. Because the flaw permits scope change, actions initiated against the vulnerable component reach resources managed by adjacent Oracle E-Business Suite products.

Exploitation requires only low-privileged credentials and produces high confidentiality impact combined with low integrity impact. Attackers can read the full set of data accessible to the module, and they can modify a limited subset of records. Availability is not affected. The Exploit Prediction Scoring System (EPSS) currently reports a probability of 0.186%, indicating limited observed exploitation activity at publication.

Root Cause

The root cause is improper access control [CWE-284]. The affected Internal Operations endpoints do not sufficiently validate that the authenticated principal is authorized to view or modify the requested regulatory management resources. The authorization gap allows a standard low-privileged Oracle E-Business Suite account to reach functionality intended for higher-privileged roles.

Attack Vector

The attack vector is network-based over HTTP. The attacker authenticates to Oracle E-Business Suite with a low-privileged account and issues crafted HTTP requests to the Internal Operations component. No user interaction is required, and attack complexity is low. Because the scope changes on successful exploitation, the impact propagates into additional Oracle E-Business Suite products integrated with Process Manufacturing Regulatory Management.

No public proof-of-concept exploit is available. Oracle has not confirmed exploitation in the wild, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Technical details are documented in the Oracle Critical Patch Update - July 2026 advisory.

Detection Methods for CVE-2026-62513

Indicators of Compromise

Unexpected HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Process Manufacturing Regulatory Management Internal Operations endpoints.
Anomalous read volume against regulatory management tables and views outside the account's normal role scope.
Unauthorized INSERT, UPDATE, or DELETE statements from application session accounts against regulatory records.
Cross-module data access patterns where a Process Manufacturing user session touches resources belonging to integrated Oracle E-Business Suite products.

Detection Strategies

Baseline HTTP request paths and parameters for the Internal Operations component and alert on deviations from role-based usage patterns.
Correlate Oracle E-Business Suite application logs with database audit records to identify privileged data access initiated by low-privileged users.
Deploy signature-based rules that flag requests to Regulatory Management URLs originating from accounts without the corresponding responsibility assignment.

Monitoring Recommendations

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking for the Process Manufacturing Regulatory Management module.
Forward web tier, application tier, and database audit logs to a centralized analytics platform for correlation.
Monitor for repeated failed authorization checks and privilege boundary crossings within the affected versions 12.2.3 through 12.2.15.

How to Mitigate CVE-2026-62513

Immediate Actions Required

Apply the Oracle Critical Patch Update from July 2026 to all Oracle E-Business Suite environments running affected versions.
Inventory all Process Manufacturing Regulatory Management deployments and identify instances between 12.2.3 and 12.2.15.
Review Oracle E-Business Suite responsibility assignments and remove excess privileges from application users.
Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted segments while patching is scheduled.

Patch Information

Oracle released the fix as part of the July 2026 Critical Patch Update. Administrators must apply the corresponding patch for Oracle Process Manufacturing Regulatory Management as documented in the Oracle Critical Patch Update - July 2026 advisory. Oracle recommends applying the CPU without delay and running the standard adop patching workflow for E-Business Suite 12.2.

Workarounds

Limit HTTP access to the Process Manufacturing Regulatory Management URLs using web application firewall rules until the patch is applied.
Enforce least-privilege responsibilities in Oracle E-Business Suite so that only required users can reach the Internal Operations component.
Enable enhanced database auditing on tables owned by the GMD and related Process Manufacturing schemas to record unauthorized data changes.
