CVE-2026-61316 Overview
CVE-2026-61316 is an information disclosure vulnerability in the Oracle EDI Gateway product of Oracle E-Business Suite. The flaw affects the Electronic Data Interchange (EDI) component in supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit this issue to gain unauthorized read access to a subset of Oracle EDI Gateway data. The vulnerability is classified under [CWE-200] Information Exposure and requires no user interaction. Oracle disclosed the issue in the July 2026 Critical Patch Update.
Critical Impact
Authenticated attackers can retrieve confidential EDI Gateway data over HTTP without user interaction, exposing a subset of business-critical transactional information.
Affected Products
- Oracle E-Business Suite - Oracle EDI Gateway 12.2.3
- Oracle E-Business Suite - Oracle EDI Gateway versions 12.2.4 through 12.2.14
- Oracle E-Business Suite - Oracle EDI Gateway 12.2.15

Technical Details for CVE-2026-61316
Vulnerability Analysis
The vulnerability resides in the Oracle EDI Gateway component of Oracle E-Business Suite. EDI Gateway handles the exchange of standardized business documents between trading partners, such as purchase orders, invoices, and shipping notices. The flaw allows a low-privileged authenticated user to reach a data path that returns information they should not be able to read. Because the attack occurs over HTTP and requires only low privileges, exploitation is straightforward within reach of any authenticated E-Business Suite account holder on the network.
Root Cause
The root cause is improper access control on data returned by the EDI Gateway component, corresponding to [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. The affected endpoint fails to enforce authorization checks proportional to the sensitivity of the underlying EDI data. As a result, users with basic authenticated access can read information intended to be restricted.
Attack Vector
Exploitation requires network access to the EDI Gateway HTTP interface and valid low-privileged credentials. The attacker interacts with the exposed EDI Gateway endpoint using standard HTTP requests. No user interaction is needed, and the attack does not modify data or affect availability. The impact is limited to confidentiality, with unauthorized read access to a subset of EDI Gateway data. See the Oracle Security Alert July 2026 for vendor technical details. No public proof-of-concept exploit is available at the time of publication.
Detection Methods for CVE-2026-61316
Indicators of Compromise
- Unusual HTTP requests from low-privileged accounts targeting Oracle EDI Gateway servlets and endpoints under the E-Business Suite application tier.
- Elevated volume of successful HTTP 200 responses to EDI Gateway data-retrieval URLs from accounts that do not normally interact with EDI trading partner data.
- Access to EDI Gateway resources from IP addresses or user sessions outside the expected trading-partner integration workflow.
Detection Strategies
- Enable and review Oracle E-Business Suite application-tier access logs and Oracle HTTP Server logs for authenticated requests to EDI Gateway URLs.
- Correlate authenticated user sessions against role assignments to identify low-privileged users touching EDI Gateway data.
- Baseline normal EDI Gateway traffic patterns and alert on deviations in request volume, source, or accessed resources.
Monitoring Recommendations
- Forward Oracle E-Business Suite audit logs, HTTP access logs, and database audit trails to a centralized SIEM for correlation.
- Alert on any account performing bulk read operations against EDI Gateway tables or views outside of scheduled integration jobs.
- Monitor for privilege changes on E-Business Suite responsibilities associated with EDI Gateway access.
How to Mitigate CVE-2026-61316
Immediate Actions Required
- Apply the July 2026 Critical Patch Update from Oracle to all Oracle E-Business Suite 12.2.3 through 12.2.15 environments running Oracle EDI Gateway.
- Inventory all E-Business Suite instances and confirm the EDI Gateway component version to prioritize patching.
- Review E-Business Suite responsibility assignments and revoke unnecessary access to EDI Gateway functionality.
Patch Information
Oracle addressed CVE-2026-61316 in the July 2026 Critical Patch Update. Administrators should download and apply the relevant patches referenced in the Oracle Security Alert July 2026. Follow Oracle's documented patching procedure for E-Business Suite 12.2, including running adop to apply application-tier patches and validating post-patch functionality in a non-production environment first.
Workarounds
- Restrict network access to the E-Business Suite application tier so only trusted internal networks and authorized integration partners can reach EDI Gateway endpoints.
- Enforce least privilege on E-Business Suite responsibilities, ensuring only accounts required for EDI processing hold EDI Gateway roles.
- Enable Oracle E-Business Suite auditing on EDI Gateway modules to increase visibility until the patch is deployed.
