CVE-2026-22014: Oracle User Management Auth Bypass Flaw

CVE-2026-22014 Overview

CVE-2026-22014 is a vulnerability in the Oracle User Management product of Oracle E-Business Suite, specifically within the Workflow and Business Events component. Affected releases span Oracle E-Business Suite versions 12.2.7 through 12.2.15. A high-privileged attacker with network access over HTTP can compromise Oracle User Management. Successful exploitation can result in unauthorized update, insert, or delete access to a subset of Oracle User Management data, along with unauthorized read access to a subset of that data. The issue is tracked under CWE-284: Improper Access Control.

Critical Impact
A high-privileged authenticated attacker can modify and read a subset of Oracle User Management data over HTTP, impacting confidentiality and integrity.

Affected Products

Oracle E-Business Suite — Oracle User Management 12.2.7
Oracle E-Business Suite — Oracle User Management 12.2.8 through 12.2.14
Oracle E-Business Suite — Oracle User Management 12.2.15

Technical Details for CVE-2026-22014

Vulnerability Analysis

The flaw resides in the Workflow and Business Events component used by Oracle User Management. The component fails to enforce sufficient access control checks on certain operations, allowing an authenticated actor with elevated privileges to perform actions on data they should not be able to alter or read. The impact is partial: only a subset of Oracle User Management accessible data is exposed to unauthorized read, update, insert, or delete operations. The current EPSS probability is 0.029%, indicating low observed exploitation interest. No public proof-of-concept has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Root Cause

The root cause maps to CWE-284: Improper Access Control. The Workflow and Business Events logic within Oracle User Management does not adequately restrict privileged operations to the intended set of authorized principals. As a result, a user already holding high privileges within the application can perform actions outside the scope of their authorization on specific data records.

Attack Vector

Exploitation requires network access to the Oracle E-Business Suite HTTP endpoints and an authenticated session with high privileges (PR:H). No user interaction is required (UI:N). Because the scope is unchanged (S:U), the impact remains within the Oracle User Management component, affecting confidentiality (C:L) and integrity (I:L) without measurable availability impact. Refer to the Oracle Security Alert April 2026 for vendor-supplied technical context.

Detection Methods for CVE-2026-22014

Indicators of Compromise

Unexpected modifications to Oracle User Management records performed by privileged accounts outside of normal change windows.
HTTP requests targeting Workflow and Business Events endpoints from administrative accounts that do not typically interact with those modules.
Audit log entries showing insert, update, or delete operations against User Management tables without an associated change ticket.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and FND audit trails for the User Management module to capture privileged data changes.
Correlate HTTP access logs at the Oracle HTTP Server tier with application-level audit events to identify privileged sessions invoking Workflow and Business Events operations.
Establish baselines for normal administrative activity in Oracle User Management and alert on deviations such as off-hours data modifications.

Monitoring Recommendations

Forward Oracle E-Business Suite application and database audit logs to a centralized SIEM for retention and correlation.
Monitor for privilege role assignments and changes to User Management responsibilities, which can precede abuse of this flaw.
Track failed and successful HTTP authentication events to privileged endpoints and alert on anomalous source addresses.

How to Mitigate CVE-2026-22014

Immediate Actions Required

Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert April 2026 to all affected Oracle E-Business Suite environments running versions 12.2.7 through 12.2.15.
Review and reduce the number of accounts holding high-privilege responsibilities in Oracle User Management.
Validate audit trail configuration and confirm logs are being shipped to a tamper-resistant store.

Patch Information

Oracle addressed this issue in the April 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert April 2026 for the specific patch identifiers, prerequisites, and post-installation steps applicable to each supported Oracle E-Business Suite release between 12.2.7 and 12.2.15.

Workarounds

Restrict network access to Oracle E-Business Suite HTTP endpoints to trusted administrative networks until patching is complete.
Temporarily remove or constrain high-privilege responsibilities in Oracle User Management that are not required for daily operations.
Increase audit log review frequency for Workflow and Business Events activity until the patch has been deployed and verified.
