CVE-2026-61114: Oracle E-Business Suite Privilege Escalation

CVE-2026-61114 Overview

CVE-2026-61114 is a vulnerability in the Oracle Application Object Library, a component of Oracle E-Business Suite. The flaw resides in the DB Privileges component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this issue, though exploitation is rated as difficult. Successful exploitation results in complete takeover of the Oracle Application Object Library, impacting confidentiality, integrity, and availability. Oracle addressed the flaw in the July 2026 Critical Patch Update.

Critical Impact
Successful exploitation allows an authenticated network attacker to take over Oracle Application Object Library, compromising all associated database privileges and application data.

Affected Products

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

Technical Details for CVE-2026-61114

Vulnerability Analysis

The vulnerability affects the DB Privileges component of Oracle Application Object Library (AOL), the foundation layer that manages user access, session context, and database privilege delegation across Oracle E-Business Suite modules. An authenticated attacker with low privileges can send crafted HTTP requests to abuse the privilege management logic and escalate control over the AOL layer.

Because AOL brokers database access for the entire E-Business Suite, a successful takeover propagates to any module that relies on AOL for authentication or privilege enforcement. The attack requires network access and valid low-privilege credentials, and Oracle rates exploitation complexity as high, indicating that specific runtime conditions or configurations are needed. Confidentiality, integrity, and availability are all fully impacted upon successful exploitation.

EPSS data places the probability of exploitation in the wild in the lower range, and no public proof-of-concept or in-the-wild exploitation has been reported at the time of publication.

Root Cause

Oracle has not published detailed technical root-cause information. Based on the advisory, the defect resides in the privilege-handling logic of the DB Privileges component within Oracle Application Object Library. Consult the Oracle Security Alert July 2026 for vendor-provided details.

Attack Vector

The attack vector is Network (AV:N) over HTTP. An attacker must hold a low-privileged account (PR:L) within the E-Business Suite environment. No user interaction is required. The vulnerability manifests through the standard HTTP interface exposed by E-Business Suite, so any accessible EBS front-end reachable by a low-privileged user represents a potential entry point.

No verified exploit code is available. Refer to the vendor advisory for exploitation prerequisites and remediation guidance.

Detection Methods for CVE-2026-61114

Indicators of Compromise

Unexpected changes to AOL user profile options, responsibility assignments, or database role grants under the APPLSYS or APPS schemas.
Anomalous HTTP requests to E-Business Suite endpoints originating from accounts with minimal assigned responsibilities.
New or modified database objects owned by APPLSYS that do not correlate with a scheduled patch or release activity.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and database auditing on privilege-related tables such as FND_USER, FND_USER_RESP_GROUPS, and FND_GRANTS.
Baseline HTTP traffic to EBS servlets and alert on low-privileged sessions issuing requests that touch privilege administration endpoints.
Correlate application-tier and database-tier logs to identify privilege changes that lack a matching administrator session.

Monitoring Recommendations

Monitor the Oracle listener and HTTP access logs for repeated failed or anomalous requests from the same low-privileged account.
Track grants issued to PUBLIC or non-administrative roles on AOL-owned objects and alert on additions.
Review scheduled concurrent programs and custom PL/SQL packages for unauthorized modifications following any suspicious session activity.

How to Mitigate CVE-2026-61114

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running Application Object Library versions 12.2.3 through 12.2.15.
Inventory all EBS instances, including non-production copies, and confirm patch levels using Oracle's AD utilities.
Rotate credentials for low-privileged application accounts if suspicious activity is observed prior to patching.

Patch Information

Oracle addressed CVE-2026-61114 as part of the Oracle Security Alert July 2026 Critical Patch Update. Administrators should apply the patch that corresponds to the installed EBS release and validate the fix through Oracle's post-patch verification steps.

Workarounds

Restrict network access to E-Business Suite HTTP endpoints so that only trusted internal networks and VPN clients can reach the application tier.
Remove or disable unused low-privileged EBS accounts and enforce least-privilege responsibility assignments until patching is complete.
Enable multi-factor authentication on all EBS user accounts to limit the value of compromised low-privilege credentials.
