CVE-2026-61026 Overview
CVE-2026-61026 is a high-severity information disclosure vulnerability in the Oracle iRecruitment product of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access over HTTP can exploit the vulnerability without user interaction. Successful exploitation grants unauthorized access to critical data or complete read access to all Oracle iRecruitment accessible data. Oracle disclosed the issue in the July 2026 Critical Patch Update advisory.
Critical Impact
Remote, unauthenticated attackers can read all data accessible through Oracle iRecruitment, exposing candidate personal data, hiring records, and internal HR information over HTTP.
Affected Products
- Oracle E-Business Suite — Oracle iRecruitment version 12.2.3
- Oracle E-Business Suite — Oracle iRecruitment versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle iRecruitment version 12.2.15

Technical Details for CVE-2026-61026
Vulnerability Analysis
CVE-2026-61026 affects the Internal Operations component of Oracle iRecruitment, a web-facing module used for candidate management and hiring workflows within Oracle E-Business Suite. The vulnerability is categorized as an information disclosure flaw with confidentiality impact only. Integrity and availability of the application remain unaffected by exploitation.
The attacker profile is minimal. No credentials, no user interaction, and no elevated privileges are required. The attack traverses the network over HTTP, making internet-exposed Oracle E-Business Suite deployments particularly exposed. The EPSS model currently estimates a probability of 0.398% for exploitation activity in the wild.
Oracle iRecruitment stores sensitive candidate and employee records including personally identifiable information (PII), resumes, and internal hiring evaluations. Unauthorized read access to this dataset carries direct privacy and regulatory implications under frameworks such as GDPR and CCPA.
Root Cause
Oracle has not published root-cause details beyond the advisory. The vulnerability is described as an easily exploitable flaw allowing unauthenticated HTTP access to protected data within the Internal Operations component. Consult the Oracle Security Alert July 2026 for vendor guidance.
Attack Vector
Exploitation occurs over the network using HTTP requests to the Oracle iRecruitment application endpoints. An attacker sends crafted requests to the Internal Operations component and retrieves data that should require authentication and authorization. Because no credentials are required, mass scanning of exposed Oracle E-Business Suite instances is a realistic pre-exploitation activity.
No public proof-of-concept code has been released. Technical exploitation details are described in prose only, per Oracle's advisory practice.
Detection Methods for CVE-2026-61026
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle iRecruitment URIs such as /OA_HTML/ and iRecruitment-specific servlet paths originating from unfamiliar external IP addresses.
- Anomalous volumes of GET requests targeting Internal Operations endpoints without a preceding authenticated session cookie.
- Application logs showing successful data responses to requests that lack a valid ICX_SESSION or Oracle E-Business Suite session token.
Detection Strategies
- Baseline normal Oracle iRecruitment traffic patterns and alert on request spikes to Internal Operations paths from single sources.
- Correlate web server access logs with authentication logs to identify data-returning responses that lack a corresponding authenticated session.
- Deploy web application firewall (WAF) rules that flag unauthenticated access attempts to Oracle E-Business Suite modules and log matches to a central SIEM.
Monitoring Recommendations
- Forward Oracle HTTP Server and application tier logs to a centralized log platform for retention and search.
- Monitor outbound data volumes from Oracle E-Business Suite tiers to detect bulk data exfiltration following unauthenticated requests.
- Track scanner user-agents and repeated 200 OK responses on iRecruitment endpoints from non-corporate address space.
How to Mitigate CVE-2026-61026
Immediate Actions Required
- Apply the July 2026 Critical Patch Update from Oracle to all Oracle E-Business Suite 12.2.3-12.2.15 deployments running iRecruitment.
- Inventory all internet-exposed Oracle E-Business Suite hosts and prioritize patching for externally reachable systems first.
- Restrict network access to iRecruitment endpoints to trusted networks or a reverse proxy that enforces authentication where business requirements allow.
Patch Information
Oracle addressed CVE-2026-61026 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 for patch identifiers, prerequisites, and installation guidance specific to their Oracle E-Business Suite 12.2.x release level.
Workarounds
- Place Oracle iRecruitment behind a reverse proxy or WAF that blocks unauthenticated requests to Internal Operations paths until patching completes.
- Disable the iRecruitment module in environments where it is not required, following Oracle's supported deactivation procedure.
- Enforce network-level access controls that limit inbound HTTP traffic to Oracle E-Business Suite tiers to known corporate ranges and VPN gateways.
