CVE-2026-61315: Oracle EDI Gateway Information Disclosure

CVE-2026-61315 Overview

CVE-2026-61315 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 vulnerability to gain unauthorized read access to a subset of Oracle EDI Gateway accessible data. The weakness is categorized under [CWE-200] (Exposure of Sensitive Information to an Unauthorized Actor). Oracle addressed the issue in the July 2026 Critical Patch Update.

Critical Impact
Authenticated attackers can retrieve confidential EDI Gateway data over HTTP, exposing business-to-business transaction information processed by Oracle E-Business Suite.

Affected Products

Oracle E-Business Suite — Oracle EDI Gateway version 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 version 12.2.15

Technical Details for CVE-2026-61315

Vulnerability Analysis

CVE-2026-61315 is an information disclosure vulnerability within the EDI component of Oracle EDI Gateway. Exploitation requires an attacker to hold valid low-privilege credentials on the target E-Business Suite instance. Once authenticated, the attacker sends crafted HTTP requests to the EDI Gateway to retrieve data they should not otherwise be permitted to view. The attack does not require user interaction and does not affect the integrity or availability of the target system. Impact is scoped to confidentiality of a subset of EDI Gateway accessible data, which typically includes trading partner records, transaction sets, and configuration metadata used in business-to-business communications.

Root Cause

The underlying weakness aligns with [CWE-200]: the EDI Gateway component fails to enforce sufficient access controls on data returned through certain HTTP-accessible interfaces. As a result, authenticated users can access records outside of the authorization boundary intended for their role. Oracle has not published root-cause details beyond what is included in the July 2026 security alert.

Attack Vector

The attack vector is network-based and delivered through HTTP requests to the Oracle EDI Gateway interface exposed by Oracle E-Business Suite. The attacker must first authenticate with low-privilege credentials, then interact with vulnerable endpoints to read protected EDI data. Because the exploitation surface is standard HTTP application traffic, no memory corruption primitives or specialized tooling are required. Public exploit code has not been observed, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2026-61315

Indicators of Compromise

Unusual volumes of authenticated HTTP requests from a single low-privilege account targeting Oracle EDI Gateway URLs under the E-Business Suite web tier.
Access patterns where a single user session enumerates EDI trading partner, transaction, or configuration records at a rate inconsistent with normal business workflows.
HTTP 200 responses to EDI Gateway endpoints from user accounts that historically have not interacted with EDI functionality.

Detection Strategies

Review Oracle E-Business Suite access logs and application server logs for repeated requests to EDI Gateway servlets or pages by low-privileged users.
Correlate authentication events with EDI Gateway data-access events to identify accounts that pivot from routine E-Business Suite activity into EDI-specific endpoints.
Baseline normal EDI Gateway usage per user role, then alert on deviations such as read access from roles that should not query EDI data.

Monitoring Recommendations

Enable and centralize logging for the Oracle HTTP Server, WebLogic managed servers, and E-Business Suite audit trails that front the EDI Gateway component.
Ingest these logs into a SIEM or data lake and create detection rules for unauthorized reads against EDI Gateway resources.
Monitor Oracle database audit logs for direct queries against EDI schema tables originating from application accounts tied to low-privilege sessions.

How to Mitigate CVE-2026-61315

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update to all Oracle E-Business Suite instances running EDI Gateway versions 12.2.3 through 12.2.15.
Inventory all E-Business Suite environments, including non-production, and confirm patch status for the EDI Gateway component.
Rotate credentials for any low-privilege accounts that exhibited anomalous access to EDI Gateway endpoints prior to patching.

Patch Information

Oracle published the fix in the July 2026 Critical Patch Update. Administrators should review the patch matrix and apply the recommended fixes listed in the Oracle Critical Patch Update Advisory - July 2026 for Oracle E-Business Suite 12.2.3–12.2.15.

Workarounds

Restrict network access to Oracle E-Business Suite EDI Gateway URLs to trusted internal networks or VPN segments until the patch is applied.
Enforce least-privilege responsibility assignments in E-Business Suite so that only users with a documented business need can authenticate to EDI Gateway functions.
Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to increase visibility into HTTP access against EDI Gateway pages.
