CVE-2026-61301: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-61301 Overview

CVE-2026-61301 is a high-severity access control vulnerability affecting the Oracle Process Manufacturing Financials 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 issue without user interaction. Successful exploitation allows unauthorized creation, deletion, or modification of critical data and grants complete read access to all Oracle Process Manufacturing Financials accessible data. The vulnerability is categorized under [CWE-284] Improper Access Control.

Critical Impact
Authenticated attackers can compromise confidentiality and integrity of all Oracle Process Manufacturing Financials data over the network with low attack complexity.

Technical Details for CVE-2026-61301

Vulnerability Analysis

The vulnerability affects the Internal Operations component of Oracle Process Manufacturing Financials, part of the broader Oracle E-Business Suite. The weakness is classified as improper access control [CWE-284]. Authorization checks fail to properly restrict actions available to low-privileged authenticated users. As a result, an attacker with a standard user account can escalate their effective data access to the full scope of Process Manufacturing Financials.

The attack is network-reachable via HTTP and requires no user interaction. Because Oracle E-Business Suite frequently stores sensitive financial records, inventory costing data, and supplier information, successful exploitation exposes business-critical assets. Both read access and write access are available to the attacker, enabling data tampering as well as data exfiltration. The EPSS probability is 0.365%, indicating a lower current likelihood of opportunistic exploitation, though targeted attacks against Oracle EBS deployments remain a persistent risk.

Root Cause

The root cause is improper enforcement of access control on operations exposed by the Internal Operations component. Server-side authorization logic does not adequately verify that the invoking user is permitted to perform the requested action on the target data. Consequently, resources that should be restricted to privileged roles are reachable by any authenticated Oracle EBS user.

Attack Vector

An attacker requires only a valid low-privileged Oracle E-Business Suite account and HTTP reachability to the application tier. The attacker submits crafted HTTP requests targeting Process Manufacturing Financials endpoints in the Internal Operations component. Because the flaw bypasses role checks, the attacker can invoke privileged data operations directly. No client-side interaction, phishing, or memory corruption primitives are required. Refer to the Oracle Security Alert July 2026 for vendor-provided technical context.

Detection Methods for CVE-2026-61301

Indicators of Compromise

Unexpected HTTP requests from low-privileged EBS accounts to Process Manufacturing Financials URLs under the Internal Operations module
Anomalous creation, modification, or deletion events in Process Manufacturing Financials tables performed by non-administrative users
Spikes in outbound data transfers correlated with authenticated EBS sessions accessing financials data

Detection Strategies

Correlate Oracle EBS application logs and database audit trails to identify data access patterns inconsistent with a user's assigned responsibilities
Enable and review Oracle FND (Foundation) audit logging for privileged forms and OA Framework pages within Process Manufacturing Financials
Deploy web application firewall rules that alert on requests to Internal Operations endpoints originating from accounts without matching business justification

Monitoring Recommendations

Continuously monitor authentication events for low-privileged EBS accounts performing bulk queries or bulk data modifications
Baseline normal Process Manufacturing Financials transaction volumes and alert on statistical deviations
Forward Oracle EBS, database, and reverse proxy logs to a centralized analytics platform for cross-source correlation and long-term retention

How to Mitigate CVE-2026-61301

Immediate Actions Required

Apply the fixes delivered in the Oracle Critical Patch Update July 2026 to all affected Oracle E-Business Suite 12.2.3–12.2.15 deployments
Inventory all EBS environments, including non-production, and confirm patch level for the Process Manufacturing Financials module
Review recent activity in Process Manufacturing Financials for unauthorized data changes performed by low-privileged accounts

Patch Information

Oracle addressed CVE-2026-61301 in the July 2026 Critical Patch Update. Administrators should download the applicable patch for their EBS 12.2.x release from My Oracle Support and apply it following Oracle's standard EBS patching procedures. Post-patch validation should include verification that Process Manufacturing Financials responsibilities enforce expected access boundaries.

Workarounds

Restrict network exposure of the Oracle E-Business Suite application tier to trusted internal networks and VPN users only
Tighten role assignments so that non-financials users do not hold responsibilities granting access to Process Manufacturing Financials functions
Enforce strong authentication and session controls on all EBS user accounts to raise the cost of obtaining the low-privilege foothold required for exploitation
