CVE-2026-61064: Oracle iRecruitment Auth Bypass Flaw

CVE-2026-61064 Overview

CVE-2026-61064 affects the Oracle iRecruitment product within Oracle E-Business Suite, specifically the Install / Upgrade Issues component. The flaw impacts supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the weakness to compromise Oracle iRecruitment. Successful exploitation permits unauthorized update, insert, or delete access to a subset of iRecruitment data, along with unauthorized read access to a subset of data.

Oracle disclosed the issue in the Oracle Security Alert July 2026. The vulnerability requires an authenticated session but no user interaction, making it accessible to any low-privilege account within reach of the application.

Critical Impact
Authenticated attackers can modify and read subsets of Oracle iRecruitment data over the network, affecting confidentiality and integrity of HR recruitment records.

Affected Products

Oracle E-Business Suite — Oracle iRecruitment 12.2.3
Oracle E-Business Suite — Oracle iRecruitment versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-61064

Vulnerability Analysis

The vulnerability resides in the Install / Upgrade Issues component of Oracle iRecruitment, a candidate-facing HR recruitment module bundled with Oracle E-Business Suite. The flaw is network-reachable over HTTP and requires low privileges, meaning any authenticated user with basic application access can attempt exploitation. No user interaction is required, and attack complexity is low.

Successful exploitation yields partial write access (update, insert, delete) and partial read access to iRecruitment data. Because iRecruitment stores personally identifiable information (PII) such as applicant records, resumes, and hiring workflow data, unauthorized modification or disclosure carries direct regulatory implications under GDPR and similar frameworks. The exploit prediction score (EPSS) indicates low near-term exploitation probability, but the low complexity means opportunistic abuse remains plausible once technical details circulate.

Root Cause

Oracle has not published detailed root-cause information beyond the component classification. The Install / Upgrade Issues designation suggests the weakness stems from insufficient access control checks or improperly scoped privileges applied during or after installation and upgrade procedures. Configuration state persisted through the upgrade path likely allows an authenticated user to reach functionality that should require higher privileges.

Attack Vector

The attack vector is network-based over HTTP against the Oracle iRecruitment web interface. An attacker requires valid low-privilege credentials to the E-Business Suite environment. From that authenticated context, the attacker issues crafted HTTP requests to iRecruitment endpoints exposed by the vulnerable component, bypassing intended authorization boundaries to read and modify records outside the account's assigned scope.

No public proof-of-concept exploit code is available. Refer to the Oracle Security Alert July 2026 for vendor-supplied technical details.

Detection Methods for CVE-2026-61064

Indicators of Compromise

Unexpected HTTP POST or PUT requests from low-privileged accounts to Oracle iRecruitment endpoints under /OA_HTML/ paths.
Database audit records showing insert, update, or delete operations on iRecruitment tables by users lacking recruiter or administrator roles.
Unusual read access patterns to applicant or vacancy tables originating from accounts without HR responsibilities.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to record authenticated activity against iRecruitment modules.
Correlate application-tier HTTP access logs with database audit trails to identify authorization boundary violations.
Baseline normal iRecruitment usage per user role and alert on deviations, particularly write operations from accounts that should have read-only or no access.

Monitoring Recommendations

Forward Oracle EBS middle-tier and database audit logs to a centralized SIEM for continuous review.
Monitor for privilege changes and unexpected responsibility assignments on user accounts with iRecruitment access.
Track HTTP 200 responses to iRecruitment endpoints following abnormal request sequences from low-privilege sessions.

How to Mitigate CVE-2026-61064

Immediate Actions Required

Apply the Oracle Critical Patch Update from July 2026 to all Oracle E-Business Suite environments running iRecruitment 12.2.3 through 12.2.15.
Inventory all accounts with any level of access to iRecruitment and enforce least privilege on responsibilities and menus.
Restrict network exposure of the Oracle E-Business Suite web tier to trusted networks and authenticated VPN users.

Patch Information

Oracle addressed CVE-2026-61064 in the July 2026 Critical Patch Update. Administrators should reference the Oracle Security Alert July 2026 for patch identifiers, prerequisites, and installation guidance specific to their EBS release level.

Workarounds

Disable the iRecruitment module if it is not in active use within the environment.
Apply web application firewall rules that restrict access to iRecruitment URLs to authorized recruiter and administrator source addresses.
Review and remove default or unused low-privilege application accounts that could be leveraged as an exploitation foothold.

bash

# Example: Restrict iRecruitment context access at the reverse proxy tier
# Replace ALLOWED_NET with your authorized CIDR ranges
location /OA_HTML/OA.jsp {
    allow ALLOWED_NET;
    deny all;
    proxy_pass http://ebs-app-tier;
