CVE-2026-62484 Overview
CVE-2026-62484 is an improper access control vulnerability [CWE-284] in the Oracle Contracts Integration 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 this weakness to compromise Oracle Contracts Integration. Successful exploitation permits unauthorized creation, deletion, or modification of critical data accessible through the product. Oracle published the fix in the July 2026 Critical Patch Update.
Critical Impact
Remote unauthenticated attackers can modify or destroy business-critical contract integration data over the network without user interaction.
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-2026-62484
Vulnerability Analysis
The vulnerability affects the Internal Operations component of Oracle Contracts Integration inside Oracle E-Business Suite. The issue is classified as improper access control under [CWE-284]. An unauthenticated attacker reaches the vulnerable functionality over HTTP without user interaction. Once reached, the attacker can create, alter, or delete data managed by Oracle Contracts Integration.
The integrity impact is high, while confidentiality and availability remain unaffected according to the CVSS vector. The high attack complexity indicates that exploitation depends on specific conditions outside the attacker's direct control, such as timing or target configuration. The EPSS score of 0.227% places exploitation likelihood in the lower percentile at the time of publication.
Root Cause
Oracle's advisory attributes the flaw to insufficient enforcement of access controls in the Internal Operations code path of Oracle Contracts Integration. The affected endpoints do not require authentication before performing data-modifying operations. This exposes contract-related records to tampering by any network-adjacent client capable of issuing HTTP requests to the Oracle E-Business Suite instance.
Attack Vector
The attack vector is network-based over HTTP. An adversary sends crafted requests to the exposed Oracle E-Business Suite endpoint that handles Contracts Integration operations. Because no authentication is required, the attacker does not need valid credentials, session tokens, or user interaction. Successful requests trigger unauthorized create, update, or delete actions against contract data. Refer to the Oracle Security Alert July 2026 for detailed technical guidance.
No public proof-of-concept code is available at the time of publication.
Detection Methods for CVE-2026-62484
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle Contracts Integration URIs, particularly endpoints tied to the Internal Operations component.
- Unexpected create, update, or delete transactions in Oracle Contracts Integration audit tables without an associated authenticated session identifier.
- Anomalous spikes in HTTP POST or PUT traffic to Oracle E-Business Suite hosts from external or unusual internal source addresses.
Detection Strategies
- Enable Oracle E-Business Suite audit logging for the Contracts Integration module and correlate data-modifying events with authentication events.
- Inspect web application firewall and reverse proxy logs for anonymous requests targeting Contracts Integration paths.
- Baseline normal Oracle E-Business Suite traffic and alert on deviations in request volume, method mix, or geographic origin.
Monitoring Recommendations
- Forward Oracle E-Business Suite application, database, and web-tier logs to a centralized SIEM for correlation.
- Alert on any successful HTTP 2xx responses to Contracts Integration endpoints from unauthenticated sessions.
- Monitor Oracle Contracts Integration tables for out-of-band DML activity outside standard change windows.
How to Mitigate CVE-2026-62484
Immediate Actions Required
- Apply the fixes delivered in the Oracle Critical Patch Update — July 2026 to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
- Inventory internet-exposed Oracle E-Business Suite deployments and restrict external access to Contracts Integration endpoints until patched.
- Review Contracts Integration audit trails for unauthorized modifications dating back to the earliest possible exposure window.
Patch Information
Oracle addressed CVE-2026-62484 in the Oracle Critical Patch Update Advisory - July 2026. Administrators must download and apply the relevant patch bundle for their Oracle E-Business Suite 12.2.x release. Oracle recommends applying Critical Patch Update fixes without delay.
Workarounds
- Place Oracle E-Business Suite behind a reverse proxy or web application firewall configured to block unauthenticated access to Contracts Integration URIs.
- Restrict network access to Oracle E-Business Suite HTTP listeners to trusted management networks using firewall rules or network segmentation.
- Disable or remove exposure of Oracle Contracts Integration endpoints if the module is not required in the environment.
