CVE-2026-70694 Overview
CVE-2026-70694 affects the Oracle Payments product within Oracle E-Business Suite, specifically the File Transmission component. The vulnerability impacts supported versions 12.2.3 through 12.2.15. A high-privileged attacker with network access via HTTP can exploit this flaw to compromise Oracle Payments. The vulnerability carries a scope change, meaning successful exploitation can impact additional products beyond Oracle Payments itself. Attackers who succeed can create, delete, or modify critical data and gain unauthorized access to all Oracle Payments accessible data.
Critical Impact
Successful exploitation results in unauthorized read, write, and delete access to critical financial payment data across Oracle Payments and adjacent products through scope change.
Affected Products
- Oracle E-Business Suite — Oracle Payments 12.2.3
- Oracle E-Business Suite — Oracle Payments versions 12.2.4 through 12.2.14
- Oracle E-Business Suite — Oracle Payments 12.2.15

Technical Details for CVE-2026-70694
Vulnerability Analysis
The flaw resides in the File Transmission component of Oracle Payments, a module handling payment file exchange between Oracle E-Business Suite and external financial systems. Exploitation requires an authenticated attacker holding high privileges within the target environment. The attack traverses the network over HTTP, meaning no local access to the server is required. Oracle rates exploitation difficulty as high, indicating that specific conditions or timing must be met for a successful attack. The scope change designation is significant here. It signals that a successful compromise of Oracle Payments propagates impact to other integrated products, expanding the blast radius beyond a single application boundary.
Root Cause
Oracle has not disclosed the underlying weakness class in the public advisory. The File Transmission component processes payment-related file operations, which typically involve parsing, validation, and inter-service communication. The Confidentiality and Integrity impact ratings without an Availability impact suggest a data access or manipulation flaw rather than a service disruption issue.
Attack Vector
An authenticated attacker with high privileges sends crafted HTTP requests to the Oracle Payments File Transmission endpoint. No user interaction is required to complete the attack chain. Because the vulnerability crosses a security scope, the attacker can affect data and functionality outside the immediate Payments module. Refer to the Oracle Security Alert for vendor-supplied technical context.
Detection Methods for CVE-2026-70694
Indicators of Compromise
- Unexpected HTTP POST or PUT requests to Oracle Payments File Transmission endpoints originating from authenticated but non-standard user sessions.
- Anomalous creation, modification, or deletion of payment transmission files or database records outside scheduled batch windows.
- Session activity from high-privileged Oracle E-Business Suite accounts performing File Transmission operations they do not typically execute.
Detection Strategies
- Baseline normal Oracle Payments File Transmission traffic and alert on deviations in request patterns, payload sizes, or endpoint access frequency.
- Correlate Oracle E-Business Suite application logs with database audit logs to identify unauthorized data modifications tied to File Transmission activity.
- Monitor scope boundary crossings by tracking data access from Oracle Payments sessions into adjacent Oracle E-Business Suite modules.
Monitoring Recommendations
- Enable Oracle E-Business Suite audit logging for all privileged accounts with access to the Payments module.
- Forward Oracle application and web server logs to a centralized SIEM for real-time correlation and long-term retention.
- Review privileged account entitlements quarterly to ensure only required users hold the elevated permissions needed to reach this attack surface.
How to Mitigate CVE-2026-70694
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert for August 2026 to all Oracle E-Business Suite instances running versions 12.2.3 through 12.2.15.
- Inventory all Oracle E-Business Suite deployments and confirm the Oracle Payments module version to prioritize patch scheduling.
- Restrict network access to Oracle Payments HTTP endpoints to trusted management networks until patching completes.
Patch Information
Oracle addresses this vulnerability in the August 2026 Critical Patch Update. Consult the Oracle Security Alert for patch identifiers, installation prerequisites, and product-specific instructions. Apply the patch across development, staging, and production environments following Oracle's recommended sequence.
Workarounds
- Enforce least privilege on Oracle E-Business Suite accounts by removing high-privilege roles from users who do not require File Transmission access.
- Place Oracle Payments behind a web application firewall configured to inspect HTTP traffic to File Transmission endpoints and block anomalous requests.
- Increase audit logging verbosity on Oracle Payments and adjacent modules to shorten detection time until the official patch is deployed.
