CVE-2026-60857 Overview
CVE-2026-60857 is a high-severity vulnerability in the Oracle Contracts Integration product of Oracle E-Business Suite, within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this issue without user interaction. Successful exploitation permits unauthorized creation, deletion, or modification of critical data, and unauthorized read access to all Oracle Contracts Integration accessible data. Oracle addressed this vulnerability in the July 2026 Critical Patch Update.
Critical Impact
Authenticated attackers over the network can achieve full read and write access to Oracle Contracts Integration data, compromising confidentiality and integrity of contract records.
Affected Products
- Oracle E-Business Suite — Oracle Contracts Integration 12.2.3
- Oracle E-Business Suite — Oracle Contracts Integration versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle Contracts Integration 12.2.15

Technical Details for CVE-2026-60857
Vulnerability Analysis
The vulnerability resides in the Internal Operations component of Oracle Contracts Integration, part of the broader Oracle E-Business Suite. An attacker who holds low-level application credentials can reach the vulnerable code path through standard HTTP traffic. The issue permits both read and write operations against contract data that should remain restricted by application-layer authorization controls.
Exploitation impacts confidentiality and integrity but does not affect availability. Because the attack surface is exposed over HTTP and requires only low privileges, the vulnerability is broadly reachable in typical Oracle E-Business Suite deployments. The EBS Contracts Integration module handles contract lifecycle data that is frequently linked to procurement, finance, and service delivery, expanding the blast radius of a successful attack.
Root Cause
Oracle has not publicly disclosed the technical root cause. Based on the CVSS metrics and impact profile, the flaw is consistent with a broken access control or authorization defect that allows an authenticated user to invoke Internal Operations functionality outside of their assigned entitlements. Refer to the Oracle Security Alert July 2026 for vendor advisory details.
Attack Vector
The attack originates from the network. The adversary authenticates with any low-privileged Oracle E-Business Suite account and issues crafted HTTP requests to the Contracts Integration endpoints exposed by the Internal Operations component. No user interaction is required and no scope change occurs. The attacker can then enumerate, read, alter, or delete data accessible to the Contracts Integration service.
No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2026-60857
Indicators of Compromise
- Unexpected HTTP requests to Oracle Contracts Integration endpoints originating from low-privileged user sessions.
- Unusual CREATE, UPDATE, or DELETE operations against contract tables outside of normal business workflows.
- Application audit log entries showing Internal Operations actions performed by accounts without contract administration roles.
Detection Strategies
- Enable and review Oracle E-Business Suite Sign-On Audit and Function Security audit trails for anomalous Contracts Integration access.
- Baseline normal HTTP traffic to /OA_HTML/ Contracts Integration URLs and alert on volume or parameter deviations.
- Correlate database-level DML activity on contract tables with the invoking application user and source IP.
Monitoring Recommendations
- Forward Oracle EBS application, middle-tier, and database audit logs to a centralized SIEM for retention and correlation.
- Alert on privilege usage patterns that show low-privileged accounts touching Internal Operations functions.
- Monitor outbound data volumes from EBS application tiers for signs of bulk contract data extraction.
How to Mitigate CVE-2026-60857
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite environments running versions 12.2.3 through 12.2.15.
- Inventory all EBS instances and confirm the Contracts Integration module status on each, prioritizing internet-exposed systems.
- Rotate credentials for any low-privileged accounts that may have been used to probe Internal Operations endpoints.
Patch Information
Oracle released the fix as part of the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2026 for patch identifiers, prerequisites, and application instructions specific to their EBS release. Test patches in a non-production environment before rolling them into production.
Workarounds
- Restrict network access to Oracle E-Business Suite front ends using firewalls, VPNs, or reverse proxies until patching is complete.
- Enforce least-privilege review of application responsibilities to reduce the pool of accounts able to reach Contracts Integration.
- Enable enhanced auditing on Contracts Integration and Internal Operations components to raise the cost of exploitation.
