CVE-2026-60434: Oracle Transportation Management Info Leak

CVE-2026-60434 Overview

CVE-2026-60434 is an authentication component vulnerability in Oracle Transportation Management, part of the Oracle Supply Chain product suite. The flaw affects version 6.5.3 and allows a low-privileged attacker with network access over HTTP to compromise confidentiality. Successful exploitation results in unauthorized read access to a subset of Oracle Transportation Management data. The vulnerability is classified as an Information Disclosure issue and was addressed in the Oracle Critical Patch Update released in July 2026.

Critical Impact
An authenticated attacker with low privileges can obtain unauthorized read access to a subset of data managed by Oracle Transportation Management through HTTP-based attacks.

Affected Products

Oracle Transportation Management version 6.5.3
Oracle Supply Chain suite (Authentication component)
Deployments exposing the Oracle Transportation Management HTTP interface to authenticated users

Technical Details for CVE-2026-60434

Vulnerability Analysis

The vulnerability resides in the Authentication component of Oracle Transportation Management. An attacker holding valid low-privilege credentials can send crafted HTTP requests to reach data that should require higher authorization. The scope remains unchanged, and only confidentiality is affected. Neither integrity nor availability of the target system is impacted. The current EPSS score is 0.215%, indicating a low probability of exploitation activity at this time.

The attack surface is limited to authenticated sessions. However, in supply chain environments where numerous internal users, partners, and integrations hold accounts, the baseline privilege requirement is easily satisfied. Read access to shipment records, routing data, or partner metadata can support reconnaissance for follow-on operations against logistics workflows.

Root Cause

Oracle has not published detailed technical internals. Based on the CVSS characterization and the component name, the root cause is an authorization weakness within the Authentication component that fails to enforce access controls on a subset of data endpoints. The pattern is consistent with Broken Access Control, where an authenticated identity can read resources beyond its assigned role.

Attack Vector

Exploitation requires network reachability to the Oracle Transportation Management HTTP interface and valid low-privilege credentials. No user interaction is needed. An attacker authenticates against the application and issues HTTP requests targeting endpoints that expose data the account should not view. The attack complexity is low, meaning no special conditions must be met beyond possessing credentials.

No public exploit code, proof-of-concept, or CISA KEV listing exists for this CVE at the time of publication. Refer to the Oracle Security Alert July 2026 for vendor-supplied context.

Detection Methods for CVE-2026-60434

Indicators of Compromise

Unusual volumes of authenticated HTTP GET requests from a single low-privilege account across Oracle Transportation Management endpoints
Access patterns where a user retrieves records associated with business units or partners outside their normal scope
Session activity originating from unexpected geographic locations or non-standard user agents against /GC3/ or related Oracle Transportation Management URLs

Detection Strategies

Enable Oracle Transportation Management audit logging and forward authenticated request logs to a central SIEM for correlation
Baseline normal per-role access patterns and alert on outliers where low-privileged accounts query high-value data resources
Inspect application logs for repetitive parameter enumeration or sequential identifier access indicative of data harvesting

Monitoring Recommendations

Monitor authentication events for account behavior deviations, including access outside business hours and rapid sequential queries
Track HTTP response sizes for authenticated sessions to identify unusually large data extractions
Correlate Oracle Transportation Management access logs with identity provider events to detect compromised credentials

How to Mitigate CVE-2026-60434

Immediate Actions Required

Apply the Oracle Critical Patch Update from July 2026 to affected Oracle Transportation Management 6.5.3 deployments
Review and reduce accounts with active low-privilege access to only those required for current business operations
Rotate credentials for service and integration accounts that connect to Oracle Transportation Management over HTTP
Restrict network access to Oracle Transportation Management interfaces to trusted management networks and VPN segments

Patch Information

Oracle addressed CVE-2026-60434 in the July 2026 Critical Patch Update. Administrators must download and apply the relevant patch for Oracle Transportation Management 6.5.3 as described in the Oracle Critical Patch Update Advisory - July 2026. Verify the patch level after installation and confirm application restart procedures complete successfully.

Workarounds

Enforce least-privilege role assignments and remove any accounts that no longer require Oracle Transportation Management access
Place Oracle Transportation Management behind a web application firewall configured to inspect authenticated HTTP traffic
Enable multi-factor authentication for all Oracle Transportation Management users to raise the cost of credential-based access
Increase logging verbosity on the Authentication component and route logs to long-term storage for investigation support
