CVE-2026-61299: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-61299 Overview

CVE-2026-61299 affects the Oracle Process Manufacturing Logistics product within Oracle E-Business Suite, specifically the Internal Operations component. The flaw allows a low-privileged attacker with network access via HTTP to compromise the application. Successful exploitation can expose all data accessible to the module and permit unauthorized update, insert, or delete operations against a subset of that data. Oracle E-Business Suite versions 12.2.3 through 12.2.15 are affected. The weakness is classified under improper access control [CWE-284].

Critical Impact
Authenticated network attackers can gain complete read access to Process Manufacturing Logistics data and modify a portion of it, undermining supply chain integrity.

Affected Products

Oracle E-Business Suite 12.2.3 through 12.2.15

Technical Details for CVE-2026-61299

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Process Manufacturing Logistics. An authenticated attacker holding low-privilege credentials can send crafted HTTP requests to the module and bypass expected access restrictions. The scope remains unchanged, but confidentiality is fully impacted while integrity is partially impacted. Availability is not affected, indicating the flaw does not disrupt service continuity but rather exposes and mutates business data. Oracle addressed the issue in the July 2026 Critical Patch Update.

Root Cause

The issue maps to [CWE-284] Improper Access Control. The affected component does not adequately validate that the authenticated principal is authorized to read or modify the requested logistics records. As a result, privilege boundaries between roles inside Oracle E-Business Suite are not enforced consistently across the Internal Operations HTTP interface.

Attack Vector

Exploitation requires network reachability to the Oracle E-Business Suite HTTP endpoints and any valid low-privileged account. No user interaction is required. An attacker submits requests to the Internal Operations interface to enumerate or manipulate logistics records outside their intended authorization boundary. The attack complexity is low, meaning no special conditions must be met beyond having an authenticated session.

No public proof-of-concept has been released, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The current EPSS probability is 0.303%. Refer to the Oracle Critical Patch Advisory for authoritative technical details.

Detection Methods for CVE-2026-61299

Indicators of Compromise

Unexpected HTTP requests from low-privileged Oracle E-Business Suite accounts targeting Process Manufacturing Logistics Internal Operations URLs.
Bulk read operations or record enumeration against logistics tables from a single session.
Unauthorized INSERT, UPDATE, or DELETE statements against Process Manufacturing Logistics tables outside normal business hours.

Detection Strategies

Correlate Oracle E-Business Suite application logs with database audit logs to identify access to logistics data that exceeds a user's assigned responsibilities.
Alert on anomalous request volume, response sizes, or query patterns from accounts that historically use only limited Internal Operations functions.
Baseline normal Process Manufacturing Logistics workflows and flag deviations in record modification patterns.

Monitoring Recommendations

Enable Oracle Fine-Grained Auditing (FGA) on sensitive Process Manufacturing Logistics tables to capture row-level access.
Forward Oracle E-Business Suite access logs, database audit trails, and web application firewall telemetry to a centralized analytics platform for correlation.
Track authentication and authorization decisions for the Internal Operations component and review privilege assignments regularly.

How to Mitigate CVE-2026-61299

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
Inventory all accounts with access to Process Manufacturing Logistics and remove unnecessary responsibilities.
Restrict network exposure of the Oracle E-Business Suite HTTP endpoints to trusted management networks.

Patch Information

Oracle released fixes for CVE-2026-61299 as part of the July 2026 Critical Patch Update. Administrators should follow the guidance in the Oracle Critical Patch Advisory and apply the referenced patches to every affected 12.2.x environment, including development, test, and disaster recovery instances.

Workarounds

Until patching is complete, tighten role and responsibility assignments in Oracle E-Business Suite so that only required users can reach the Internal Operations component.
Deploy web application firewall rules to restrict access to Process Manufacturing Logistics URLs by source IP and authenticated role.
Increase audit logging verbosity on the affected component and review logs daily for signs of unauthorized data access.

bash

# Example: restrict access to Process Manufacturing Logistics URLs at the web tier
# (Apply within Oracle HTTP Server httpd.conf or a fronting reverse proxy)
<LocationMatch "^/OA_HTML/.*OPMLogistics.*">
    Order deny,allow
    Deny from all
