CVE-2026-62497: Oracle Flow Manufacturing Auth Bypass

CVE-2026-62497 Overview

CVE-2026-62497 is a high-severity access control vulnerability [CWE-284] in Oracle Flow Manufacturing, a component of Oracle E-Business Suite. The flaw affects the Internal Operations component in supported versions 12.2.13 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this vulnerability to compromise Oracle Flow Manufacturing. Successful exploitation grants unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all data accessible through Oracle Flow Manufacturing. Oracle addressed the issue in the Oracle Critical Patch Update - July 2026.

Critical Impact
An authenticated attacker with low privileges can compromise the confidentiality and integrity of all data accessible through Oracle Flow Manufacturing over the network.

Technical Details for CVE-2026-62497

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Flow Manufacturing within Oracle E-Business Suite. It is classified under [CWE-284] Improper Access Control. An attacker only requires low-level authenticated access and network reachability over HTTP to trigger the flaw. Exploitation does not require user interaction and is rated as low complexity by Oracle.

Successful attacks yield two primary outcomes. First, attackers gain unauthorized write access, enabling creation, deletion, or modification of critical Flow Manufacturing data. Second, attackers obtain unauthorized read access to all data reachable through the module. Availability is not impacted, which suggests the vulnerability enables data-layer manipulation rather than service disruption.

Root Cause

The root cause is improper enforcement of access controls within the Internal Operations component. Access decisions do not adequately restrict a low-privileged authenticated user from invoking sensitive operations or reading records outside their authorization scope. The condition falls under the CWE-284 category, which covers cases where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Attack Vector

The attack vector is network-based over HTTP, targeting the Oracle E-Business Suite web interface exposing Flow Manufacturing functionality. The attacker must hold a valid low-privileged account on the target instance. Once authenticated, the attacker issues crafted HTTP requests to Internal Operations endpoints to read, create, modify, or delete data beyond their intended privileges. No exploit code is publicly available at time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

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

Detection Methods for CVE-2026-62497

Indicators of Compromise

Anomalous HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Flow Manufacturing Internal Operations endpoints.
Unexpected creation, deletion, or modification of Flow Manufacturing records outside standard business workflows.
Bulk read operations against Flow Manufacturing tables originating from accounts without prior history of such access.

Detection Strategies

Enable Oracle E-Business Suite audit logging for the Flow Manufacturing module and review privileged data operations performed by non-privileged users.
Correlate application-layer audit events with web server access logs to identify HTTP requests that trigger unauthorized data changes.
Baseline normal user access patterns for Flow Manufacturing and alert on deviations, particularly around bulk record enumeration or modification.

Monitoring Recommendations

Forward Oracle E-Business Suite application logs, database audit logs, and web tier logs to a centralized SIEM for correlation.
Monitor for authentication events from accounts with low privileges that immediately access Flow Manufacturing Internal Operations URLs.
Track database-level changes to Flow Manufacturing tables and flag modifications performed outside change-management windows.

How to Mitigate CVE-2026-62497

Immediate Actions Required

Apply the Oracle July 2026 Critical Patch Update to all Oracle E-Business Suite instances running Flow Manufacturing versions 12.2.13 through 12.2.15.
Inventory all Oracle E-Business Suite environments, including non-production, and confirm patch status for the Flow Manufacturing component.
Review recent activity in Flow Manufacturing audit logs for signs of unauthorized data access or modification.

Patch Information

Oracle released fixes for CVE-2026-62497 as part of the July 2026 Critical Patch Update. Administrators should download and apply the patches referenced in the Oracle Security Alert - July 2026. Follow Oracle's documented patch application procedures for Oracle E-Business Suite 12.2, including any prerequisite patches for the technology stack.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints so only authorized users and internal networks can reach the Flow Manufacturing module.
Review and tighten role assignments in Oracle E-Business Suite to remove unnecessary access to Flow Manufacturing responsibilities.
Enforce web application firewall rules that inspect and rate-limit requests to Internal Operations URLs pending patch deployment.
