CVE-2026-61005: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-61005 Overview

CVE-2026-61005 is a high-severity vulnerability in the Oracle Process Manufacturing Logistics product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this vulnerability without user interaction. Successful exploitation allows unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to all data accessible through Oracle Process Manufacturing Logistics. Oracle addressed this issue in the Oracle Security Alert July 2026.

Critical Impact
Attackers with low privileges can compromise the confidentiality and integrity of all data accessible to Oracle Process Manufacturing Logistics over the network.

Technical Details for CVE-2026-61005

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Process Manufacturing Logistics, a module within Oracle E-Business Suite. Oracle's advisory classifies the issue as easily exploitable over HTTP by an authenticated attacker holding low privileges. The impact extends beyond a single record set. According to Oracle, a successful attack can result in unauthorized creation, deletion, or modification of critical data, and unauthorized read access to all data reachable by the affected module. Availability is not impacted, but confidentiality and integrity are fully compromised within the module's data scope. The EPSS score is 0.365% with a percentile of 29.035, indicating limited observed exploitation activity at publication time.

Root Cause

Oracle has not published detailed root-cause information for CVE-2026-61005. The advisory attributes the flaw to the Internal Operations component and confirms that no user interaction is required. Based on the impact profile — arbitrary read and write access across the module's data — the flaw is consistent with a broken access control or improper authorization issue affecting HTTP-exposed operations.

Attack Vector

Exploitation requires network access to the Oracle E-Business Suite HTTP interface and authenticated credentials at any privilege level. The attacker sends crafted HTTP requests to the Internal Operations component of Oracle Process Manufacturing Logistics. No user interaction, phishing, or client-side prerequisite is required. Because Oracle E-Business Suite is frequently exposed to internal enterprise networks and, in some deployments, to the internet through reverse proxies, the attack surface can be broad. Oracle has not disclosed technical proof-of-concept details. See the Oracle Security Alert July 2026 for the vendor's authoritative description.

Detection Methods for CVE-2026-61005

Indicators of Compromise

Unexpected HTTP requests to Oracle Process Manufacturing Logistics Internal Operations endpoints originating from low-privileged user sessions.
Unauthorized create, update, or delete operations recorded in Oracle E-Business Suite audit logs for OPM Logistics tables.
Anomalous read queries returning large volumes of logistics data outside a user's normal role scope.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and application-level auditing on OPM Logistics modules to capture user activity and privilege usage.
Correlate application audit records with web tier access logs to identify sessions issuing unusual HTTP request patterns.
Baseline normal transaction volumes per user role and alert on deviations, particularly bulk data reads or writes.

Monitoring Recommendations

Forward Oracle E-Business Suite web tier, database audit, and FND_LOG records to a centralized SIEM for correlation.
Monitor for authentication events followed by immediate high-volume access to Internal Operations URLs.
Track privilege changes and role assignments in FND_USER and WF_USER_ROLES for unauthorized escalation attempts.

How to Mitigate CVE-2026-61005

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
Inventory all Oracle E-Business Suite deployments and identify systems exposing OPM Logistics to untrusted networks.
Restrict HTTP access to the E-Business Suite web tier to trusted network segments until patching is complete.
Review recent audit logs for signs of unauthorized data access or modification within OPM Logistics.

Patch Information

Oracle released the fix as part of the July 2026 Critical Patch Update. Administrators should download and apply the patch via My Oracle Support and follow Oracle's documented patch application procedures for E-Business Suite. Refer to the Oracle Security Alert July 2026 for patch identifiers and prerequisite guidance.

Workarounds

Enforce least-privilege role assignments and remove unnecessary access to OPM Logistics responsibilities.
Place the Oracle E-Business Suite web tier behind a web application firewall configured to block anomalous requests to Internal Operations endpoints.
Require VPN or zero-trust network access for users accessing OPM Logistics until patches are deployed.
