Technical Details for CVE-2026-62450

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Flow Manufacturing, part of the Oracle E-Business Suite. Oracle Flow Manufacturing manages flow schedules, line balancing, and mixed-model production, and integrates with other E-Business Suite modules over HTTP. The flaw is remotely reachable and does not require user interaction. An attacker holding low privileges within the application can drive the vulnerable Internal Operations functionality to compromise the product. According to Oracle's advisory, a successful attack results in takeover of Oracle Flow Manufacturing, indicating impact on stored manufacturing data, transactional integrity, and service availability.

Root Cause

Oracle has not published root-cause technical details in the public advisory. The disclosure lists the affected component (Internal Operations) and confirms that low-privileged HTTP access is sufficient to reach the vulnerable code path. Refer to the Oracle Security Alert August 2026 for the authoritative fix and product bulletin.

Attack Vector

Exploitation occurs over the network via HTTP. The attacker must hold a valid low-privileged application session, but no user interaction is required and the attack complexity is low. The EPSS score is 0.447% with a percentile of 37.381 as of 2026-08-20, indicating no observed in-the-wild exploitation at this time. No public proof-of-concept or exploit code has been released.

No verified exploitation code is available. See the vendor advisory linked above for technical details.

Detection Methods for CVE-2026-62450

Indicators of Compromise

Unexpected HTTP requests to Oracle Flow Manufacturing Internal Operations endpoints originating from user accounts that do not normally interact with manufacturing modules.
New or modified Flow Manufacturing schedules, routings, or line configurations created outside of change-management windows.
Oracle E-Business Suite application logs showing privilege changes or administrative operations performed by low-privileged accounts.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to correlate low-privileged sessions with access to Flow Manufacturing forms.
Baseline normal HTTP traffic patterns to /OA_HTML/ and Flow Manufacturing servlets, then alert on anomalous POST volumes or parameter tampering.
Correlate database audit trails on Flow Manufacturing schema objects (MRP, WSM, FLM) with application-tier session identifiers to surface unauthorized writes.

Monitoring Recommendations

Forward Oracle E-Business Suite middle-tier and Apache access logs to a centralized SIEM for retention and analytics.
Alert on authentication events for accounts that suddenly access Flow Manufacturing responsibilities they have not previously used.
Monitor outbound network activity from Oracle E-Business Suite application servers for signs of post-compromise command-and-control.

How to Mitigate CVE-2026-62450

Immediate Actions Required

Apply the patches referenced in the Oracle Security Alert August 2026 to all affected Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Inventory all Oracle Flow Manufacturing deployments and prioritize internet-adjacent instances for immediate remediation.
Review recent Flow Manufacturing activity for signs of unauthorized configuration changes prior to patching.

Patch Information

Oracle released fixes for CVE-2026-62450 as part of the Oracle Security Alert of August 2026. Administrators must apply the patch corresponding to their Oracle E-Business Suite 12.2 patch level. Confirm patch application by verifying the updated module versions in AD_BUGS after the patching cycle completes.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints so that only trusted internal networks and VPN users can reach the application tier.
Remove or restrict Flow Manufacturing responsibilities from user accounts that do not require them, minimizing the pool of low-privileged accounts that can reach the vulnerable component.
Deploy a web application firewall in front of the Oracle E-Business Suite application tier to inspect and rate-limit requests to Flow Manufacturing URLs until patches are applied.

bash

# Configuration example: restrict access to Flow Manufacturing URLs at the reverse proxy
# Example Apache httpd snippet — adapt paths to your EBS deployment
<LocationMatch "/OA_HTML/.*(Flm|WSM).*">
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
