CVE-2026-60687 Overview
CVE-2026-60687 is a vulnerability in the Oracle U.S. Federal Financials product of Oracle E-Business Suite, specifically within the Internal Operations component. Affected releases span versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access via HTTPS can exploit the flaw, though exploitation is rated as difficult. Successful attacks result in unauthorized access to critical data or complete access to all Oracle U.S. Federal Financials accessible data. The vulnerability carries a scope change, meaning attacks may significantly impact additional products beyond the vulnerable component.
Critical Impact
Unauthenticated network attackers can obtain unauthorized access to critical or all Oracle U.S. Federal Financials data, with impact extending to additional Oracle products through scope change.
Affected Products
- Oracle E-Business Suite - Oracle U.S. Federal Financials 12.2.3 through 12.2.15
- Component: Internal Operations
- Additional products impacted through scope change (not enumerated in advisory)

Technical Details for CVE-2026-60687
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle U.S. Federal Financials, part of the broader Oracle E-Business Suite. An unauthenticated attacker can reach the vulnerable code path over HTTPS without requiring credentials or user interaction. Exploitation is characterized as difficult, indicating that specific conditions or timing must be met for a successful attack.
A scope change is present, meaning a successful compromise of Oracle U.S. Federal Financials may extend to other Oracle components sharing trust relationships. The confidentiality impact is high, while integrity and availability are unaffected. This profile indicates an information disclosure vulnerability rather than one enabling code execution or data modification.
Root Cause
Oracle has not published detailed root cause information in public advisories. The Oracle Critical Patch Update July 2026 references the fix but does not disclose the underlying weakness class. No CWE mapping has been assigned in the NVD entry at the time of publication. Refer to the Oracle Security Alert July 2026 for vendor-supplied context.
Attack Vector
The attack vector is network-based over HTTPS. The attacker requires no authentication and no user interaction. Because Oracle U.S. Federal Financials is typically deployed in restricted government or enterprise environments, an attacker would first need reachability to the application's HTTPS endpoint. Exploitation complexity is elevated, suggesting that reliable exploitation may depend on environmental factors or specific request sequencing.
No public proof-of-concept exploit or exploitation-in-the-wild reporting has been observed. The EPSS probability is 0.257% with a percentile of 17.26, indicating a low current likelihood of exploitation activity.
Detection Methods for CVE-2026-60687
Indicators of Compromise
- Unexpected HTTPS requests to Oracle E-Business Suite Internal Operations endpoints from external or unusual internal sources
- Anomalous data egress volumes from hosts running Oracle U.S. Federal Financials 12.2.3 through 12.2.15
- Access to sensitive Federal Financials records outside of documented business workflows
Detection Strategies
- Enable and review Oracle E-Business Suite audit logs for Internal Operations module access patterns
- Correlate web application firewall (WAF) logs with backend Oracle EBS access logs to identify unauthenticated request chains
- Baseline normal query patterns against the Federal Financials schema and alert on statistical deviations
Monitoring Recommendations
- Forward Oracle E-Business Suite application, database, and HTTPS access logs to a centralized logging platform for retention and analytics
- Monitor for outbound connections from EBS application tiers to non-approved destinations
- Track configuration and patch state of all 12.2.x Oracle EBS deployments to identify unpatched instances
How to Mitigate CVE-2026-60687
Immediate Actions Required
- Inventory all Oracle E-Business Suite deployments and identify instances running Oracle U.S. Federal Financials versions 12.2.3 through 12.2.15
- Apply the July 2026 Oracle Critical Patch Update to affected environments as the primary remediation
- Restrict network exposure of Oracle EBS HTTPS endpoints to trusted networks and required user populations only
- Review audit logs for the period preceding patch application to identify possible prior access
Patch Information
Oracle addressed CVE-2026-60687 in the July 2026 Critical Patch Update. Administrators should review the Oracle Security Alert July 2026 advisory and apply the corresponding patch bundle for Oracle E-Business Suite 12.2. Oracle does not typically provide standalone security patches outside of the quarterly CPU cycle, so applying the full CPU is required.
Workarounds
- Place Oracle EBS behind a reverse proxy or WAF with strict allow-listing of source IP ranges until patching is complete
- Enforce network segmentation to isolate Oracle EBS application tiers from general enterprise and internet-facing networks
- Disable or restrict access to the Internal Operations component if it is not required for business operations, pending vendor guidance
