CVE-2026-62498: Oracle Flow Manufacturing Escalation Flaw

CVE-2026-62498 Overview

CVE-2026-62498 is a high-severity vulnerability in the Oracle Flow Manufacturing product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.7 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit the weakness to fully compromise Oracle Flow Manufacturing. Successful exploitation results in complete takeover of the affected product, impacting confidentiality, integrity, and availability. The vulnerability is categorized under CWE-269: Improper Privilege Management.

Critical Impact
Authenticated network attackers can take over Oracle Flow Manufacturing installations, gaining full read, write, and disruption capabilities across the module.

Technical Details for CVE-2026-62498

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Flow Manufacturing. An authenticated user with minimal privileges can send crafted HTTP requests to the module and elevate their effective permissions within the application. Because the attack requires only low privileges and no user interaction, any account with routine access to the Oracle E-Business Suite web tier can serve as a launch point. The exploitability score on EPSS is 0.362%, indicating limited observed exploitation activity at publication time.

Root Cause

Oracle classifies the weakness under CWE-269: Improper Privilege Management. The Internal Operations component fails to enforce privilege boundaries on specific operations, allowing a user session assigned to a lower-privileged role to invoke functionality reserved for administrative or system contexts. This design gap breaks the least-privilege model expected within Oracle E-Business Suite deployments.

Attack Vector

The attack vector is network-based over HTTP. An attacker authenticates to the Oracle E-Business Suite front end using any valid low-privileged account, then issues requests to endpoints exposed by the Flow Manufacturing Internal Operations component. Because the flaw affects confidentiality, integrity, and availability at high impact, the attacker can read protected manufacturing data, alter production records, and disrupt operations. Refer to the Oracle Security Alert July 2026 for endpoint-level technical guidance.

Detection Methods for CVE-2026-62498

Indicators of Compromise

Unexpected HTTP POST or GET requests to Oracle Flow Manufacturing Internal Operations URLs from low-privileged user sessions.
Application audit records showing privileged actions (configuration changes, data exports, workflow modifications) tied to non-administrative Oracle E-Business Suite accounts.
New or altered records in Flow Manufacturing tables without a corresponding change ticket or administrative session.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to correlate user roles with sensitive Internal Operations endpoints.
Baseline normal Flow Manufacturing usage per role and alert on deviations, particularly on any privileged function invoked by a non-privileged responsibility.
Ingest Oracle E-Business Suite application, database, and web tier logs into a centralized analytics platform to identify anomalous request patterns across 12.2.x installations.

Monitoring Recommendations

Monitor the Oracle HTTP Server access logs for repeated calls to Flow Manufacturing URLs originating from a single low-privileged session.
Track FND_LOGINS, FND_UNSUCCESSFUL_LOGINS, and Oracle Workflow tables for privilege changes not initiated by administrators.
Alert on any modification to responsibilities, menus, or function security assignments outside approved change windows.

How to Mitigate CVE-2026-62498

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite 12.2.7 through 12.2.15 environments running Oracle Flow Manufacturing.
Review and reduce assignment of the Flow Manufacturing responsibility to only users who require it, limiting the pool of accounts that can reach the vulnerable component.
Rotate credentials for accounts that had access to Flow Manufacturing during the exposure window and audit their recent activity.

Patch Information

Oracle addressed CVE-2026-62498 in the July 2026 Critical Patch Update. Full remediation details, patch numbers, and version-specific instructions are available in the Oracle Security Alert July 2026. Administrators should schedule patch deployment following Oracle's recommended procedure for E-Business Suite 12.2 including application of the corresponding AD and TXK prerequisites where required.

Workarounds

Restrict network access to the Oracle E-Business Suite web tier using firewall rules or reverse proxy allow-lists until the patch is applied.
Temporarily remove or disable Flow Manufacturing responsibilities from user profiles that do not require operational access.
Increase logging verbosity on the Internal Operations component to capture forensic evidence during the mitigation period.

bash

# Example: restrict Flow Manufacturing responsibility via SQL*Plus
sqlplus apps/<password>
EXEC fnd_user_pkg.delresp('USERNAME','FND','FLM_INTERNAL_OPS','STANDARD');
