CVE-2026-62470 Overview
CVE-2026-62470 is an information disclosure vulnerability in the Oracle Self-Service Human Resources product of Oracle E-Business Suite, specifically within the Manager Self-Service component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the vulnerability to gain unauthorized access to sensitive HR data. Successful exploitation can result in complete read access to all data accessible through Oracle Self-Service Human Resources. The issue is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor).
Critical Impact
An authenticated attacker with minimal privileges can retrieve confidential employee, payroll, and organizational data managed by Oracle Self-Service Human Resources.
Affected Products
- Oracle E-Business Suite - Oracle Self-Service Human Resources 12.2.3
- Oracle E-Business Suite - Oracle Self-Service Human Resources versions 12.2.4 through 12.2.14
- Oracle E-Business Suite - Oracle Self-Service Human Resources 12.2.15

Technical Details for CVE-2026-62470
Vulnerability Analysis
The vulnerability resides in the Manager Self-Service component of Oracle Self-Service Human Resources. It permits a low-privileged authenticated user to access HR records that should be restricted by the application's authorization model. The confidentiality impact is high, while integrity and availability are unaffected. This behavior is consistent with a broken access control condition that exposes sensitive data over standard HTTP requests.
Oracle E-Business Suite deployments frequently store payroll, personally identifiable information (PII), and organizational hierarchy data. Unauthorized read access to this dataset creates downstream risk including targeted phishing, insider fraud, and regulatory exposure under GDPR, HIPAA, and similar frameworks. The EPSS score is 0.27% at the 18.962 percentile as of 2026-07-22, indicating low observed exploitation activity but non-trivial theoretical risk given the low attack complexity.
Root Cause
The underlying weakness maps to [CWE-200]. The Manager Self-Service component fails to enforce proper authorization checks before returning HR data to the requesting user. Any account with valid session credentials, regardless of assigned role, can query resources beyond its intended scope.
Attack Vector
Exploitation occurs over the network via HTTP against an exposed Oracle E-Business Suite instance. The attacker must hold a low-privileged application account, which is common in large enterprise deployments where thousands of employees have Self-Service access. No user interaction is required, and the attack complexity is low.
No public exploit code is available and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Oracle Security Alert July 2026 for authoritative technical guidance.
Detection Methods for CVE-2026-62470
Indicators of Compromise
- Unusual volumes of HTTP requests from a single authenticated Self-Service user to Manager Self-Service endpoints.
- Access patterns where a low-privileged user retrieves records for employees outside their reporting hierarchy.
- Repeated enumeration of employee IDs or organizational identifiers in URL parameters or POST bodies.
Detection Strategies
- Review Oracle E-Business Suite application audit logs for anomalous queries against Self-Service Human Resources modules.
- Correlate web server access logs with directory group memberships to identify authorization mismatches.
- Deploy web application firewall (WAF) rules to alert on rapid parameter iteration against Manager Self-Service URLs.
Monitoring Recommendations
- Baseline expected data access volumes per user role and alert on deviations exceeding the baseline.
- Forward Oracle E-Business Suite logs to a centralized SIEM for correlation with identity and network telemetry.
- Monitor outbound data transfers from Oracle E-Business Suite application tiers for signs of bulk exfiltration.
How to Mitigate CVE-2026-62470
Immediate Actions Required
- Apply the fixes documented in the Oracle Critical Patch Update for July 2026 to all affected Oracle E-Business Suite instances.
- Inventory all installations of Oracle Self-Service Human Resources versions 12.2.3 through 12.2.15 across production and non-production environments.
- Restrict network exposure of Oracle E-Business Suite front-end tiers to trusted networks or VPN access where feasible.
- Rotate credentials for accounts suspected of unauthorized use following the audit review.
Patch Information
Oracle addressed CVE-2026-62470 in the July 2026 Critical Patch Update. Administrators should download and apply the patch bundle referenced in the Oracle Security Alert July 2026. Oracle recommends applying Critical Patch Update fixes without delay.
Workarounds
- Limit Self-Service Human Resources access to users with a business need until patching completes.
- Enforce multi-factor authentication (MFA) on all Oracle E-Business Suite accounts to raise the cost of credential-based access.
- Deploy WAF rules that constrain access to Manager Self-Service endpoints based on user identity and role attributes.
- Increase audit logging verbosity on affected modules to support forensic review while the patch is being tested.
