CVE-2026-61111: Oracle E-Business Suite Auth Bypass Flaw

CVE-2026-61111 Overview

CVE-2026-61111 affects the Oracle Application Object Library (FNDLOAD/AOL) component within Oracle E-Business Suite. The vulnerability impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with logon access to the infrastructure where Oracle Application Object Library executes can exploit this flaw. Successful exploitation results in unauthorized access to critical data or complete access to all Oracle Application Object Library accessible data. The vulnerability produces a scope change, meaning attacks can significantly impact additional Oracle products beyond the vulnerable component.

Critical Impact
Local authenticated attackers can achieve high confidentiality impact across Oracle E-Business Suite components through a scope-changing vulnerability in the Application Object Library core.

Affected Products

Oracle E-Business Suite Application Object Library version 12.2.3
Oracle E-Business Suite Application Object Library versions 12.2.4 through 12.2.14
Oracle E-Business Suite Application Object Library version 12.2.15

Technical Details for CVE-2026-61111

Vulnerability Analysis

The vulnerability resides in the Core component of Oracle Application Object Library, a foundational layer providing shared services across Oracle E-Business Suite modules. An attacker requires local access and low privileges to exploit the flaw. No user interaction is required. The scope change indicator signals that a successful attack transcends the vulnerable component and reaches resources managed by a different security authority. This behavior expands the blast radius to related E-Business Suite products relying on the Application Object Library.

The vulnerability impacts only confidentiality. Integrity and availability remain unaffected according to the published CVSS vector. Oracle classifies the attack complexity as low, indicating repeatable exploitation without specialized conditions.

Root Cause

Oracle has not published detailed root-cause information beyond the Critical Patch Update advisory. The Core component of Application Object Library handles shared services such as concurrent processing, profile options, and message dictionary access. Improper access control within these shared services allows a locally authenticated user to read data belonging to other users or modules processed by the Application Object Library.

Attack Vector

Exploitation requires an authenticated session on the host running Oracle E-Business Suite. The attacker leverages standard user privileges on the infrastructure and issues requests that traverse the vulnerable Application Object Library code path. Because the scope changes, the returned data may originate from adjacent E-Business Suite modules such as Financials, Human Resources, or Purchasing. Refer to the Oracle Security Alert for July 2026 for advisory-level detail. No public proof-of-concept code has been observed at the time of writing.

Detection Methods for CVE-2026-61111

Indicators of Compromise

Unexpected FNDLOAD or Application Object Library utility executions initiated by non-administrative Oracle E-Business Suite users
Anomalous access patterns against FND_* database objects, particularly outside standard batch schedules
Local shell sessions on the E-Business Suite application tier from accounts that normally interact only through the web interface

Detection Strategies

Correlate operating system authentication logs on the E-Business Suite mid-tier with concurrent Oracle audit trail entries for the APPLSYS and APPS schemas
Baseline typical Application Object Library invocation patterns and alert on deviations in frequency, source user, or accessed profile options
Enable Oracle Unified Auditing for sensitive Application Object Library packages and forward logs to a centralized analytics platform

Monitoring Recommendations

Ingest Oracle E-Business Suite application-tier host telemetry, database audit logs, and middleware logs into a unified analytics platform for cross-source correlation
Monitor for privilege enumeration commands executed by low-privileged OS accounts on the application server
Track outbound data volumes from the E-Business Suite host to detect bulk extraction consistent with confidentiality compromise

How to Mitigate CVE-2026-61111

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 application-tier hosts and confirm the patch level of the Application Object Library component
Review and reduce the population of accounts with interactive logon rights to the E-Business Suite infrastructure

Patch Information

Oracle addressed CVE-2026-61111 in the July 2026 Critical Patch Update. Administrators should follow the guidance in the Oracle Security Alert for July 2026 and apply the corresponding patch for their version. Oracle recommends applying Critical Patch Update fixes without delay.

Workarounds

Restrict operating system logon access to the E-Business Suite application tier to a minimal set of administrators
Enforce strong session controls and multi-factor authentication for any accounts permitted to log on to the infrastructure
Segment the E-Business Suite hosts on a management network with strict access controls until patching completes
