CVE-2026-70791: Oracle Transportation Execution Auth Bypass

CVE-2026-70791 Overview

CVE-2026-70791 is a high-severity vulnerability in the Oracle Transportation Execution product of Oracle E-Business Suite, specifically within the Internal Operations component. The flaw affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTP can exploit the vulnerability, though successful attacks require human interaction from a user other than the attacker. Exploitation crosses a security scope boundary, meaning attacks may significantly impact additional products beyond Oracle Transportation Execution. Successful exploitation can result in unauthorized creation, deletion, or modification of critical data, as well as unauthorized read access to a subset of Oracle Transportation Execution data.

Critical Impact
An authenticated attacker can trick a legitimate user into an HTTP interaction that grants unauthorized write access to critical Oracle Transportation Execution data and limited read access, with impact extending across the security scope to additional Oracle E-Business Suite components.

Affected Products

Oracle E-Business Suite — Oracle Transportation Execution 12.2.3
Oracle E-Business Suite — Oracle Transportation Execution versions 12.2.4 through 12.2.14
Oracle E-Business Suite — Oracle Transportation Execution 12.2.15

Technical Details for CVE-2026-70791

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Transportation Execution, a module of Oracle E-Business Suite that manages transportation planning, execution, and settlement workflows. The flaw is described by Oracle as easily exploitable over HTTP. It requires authentication at a low privilege level and coerced interaction from a separate user, typically an authenticated operator or administrator.

Because the vulnerability produces a scope change, code executing in the compromised Transportation Execution context can influence data or functionality in adjacent Oracle E-Business Suite modules. The primary impact is on data integrity, allowing unauthorized creation, deletion, or modification of records handled by Transportation Execution. Confidentiality impact is limited to a subset of accessible data, and there is no direct availability impact.

Root Cause

Oracle has not disclosed the underlying weakness class, and no CWE identifier is assigned in the NVD entry. The combination of low privilege, HTTP attack vector, required user interaction, and scope change is consistent with web application flaws such as cross-site request forgery or reflected input handling issues in a privileged workflow. Refer to the Oracle Security Alert for authoritative technical details.

Attack Vector

An attacker authenticates to Oracle Transportation Execution with low privileges and then induces another user to perform an HTTP-triggered action. That interaction causes the application to execute state-changing operations under the victim's privileges. The scope change indicates the resulting operations affect resources managed by a different security authority than the originally vulnerable component.

No verified public proof-of-concept code is available. The EPSS score is 0.262% (percentile 18.17) as of 2026-08-20, indicating limited near-term exploitation likelihood based on current signals.

Detection Methods for CVE-2026-70791

Indicators of Compromise

Unexpected create, update, or delete operations against Transportation Execution records outside of scheduled batch windows or normal user workflows.
HTTP requests to Internal Operations endpoints originating from external referrers or containing anomalous parameters.
Audit trail entries showing privileged actions initiated shortly after a user clicked an external link or opened an email.

Detection Strategies

Enable and centralize Oracle E-Business Suite application-level audit logging for the Transportation Execution module and forward events to a SIEM for correlation.
Baseline typical user behavior for Internal Operations endpoints and alert on deviations in request volume, source IP, or user-agent.
Correlate web server access logs with application audit records to identify HTTP-triggered state changes without a corresponding user-initiated session flow.

Monitoring Recommendations

Monitor for cross-origin POST requests targeting Transportation Execution URLs and requests that lack expected anti-CSRF tokens.
Alert on privileged data modifications performed by low-privilege accounts.
Track authentication events from unusual geolocations followed by state-changing HTTP calls to Internal Operations endpoints.

How to Mitigate CVE-2026-70791

Immediate Actions Required

Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to all Oracle E-Business Suite 12.2.3 through 12.2.15 environments.
Inventory all Oracle Transportation Execution instances and confirm patch level after remediation.
Restrict network access to Oracle E-Business Suite web tiers so that only trusted client networks can reach Internal Operations endpoints.
Enforce security awareness reminders for users who interact with Transportation Execution, given the required user-interaction element.

Patch Information

Oracle addressed this vulnerability in the August 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert for the specific patch identifiers applicable to their Oracle E-Business Suite 12.2 release and apply fixes according to Oracle's documented procedure.

Workarounds

Place Oracle E-Business Suite web tiers behind a reverse proxy or web application firewall that enforces strict referrer and origin checks on state-changing requests.
Reduce the number of accounts with access to Oracle Transportation Execution to the minimum required for business operations.
Configure session timeouts and require re-authentication before sensitive Internal Operations actions to limit the window for coerced interaction.

bash

# Example: restrict access to the E-Business Suite web tier at the network layer
# Allow only the internal application network to reach the Oracle HTTP Server
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
