CVE-2026-60176: Oracle Payments Auth Bypass Vulnerability

CVE-2026-60176 Overview

CVE-2026-60176 affects the Oracle Payments product within Oracle E-Business Suite, specifically the File Transmission component. Supported versions 12.2.3 through 12.2.15 are affected. A low-privileged attacker with network access via HTTP can exploit this vulnerability to compromise Oracle Payments. Successful exploitation results in unauthorized access to critical Oracle Payments data and can cause a partial denial of service. The weakness is categorized under [CWE-200] Information Exposure.

Critical Impact
Attackers with low-level authenticated access can read all data accessible to Oracle Payments and cause partial service disruption over the network.

Technical Details for CVE-2026-60176

Vulnerability Analysis

The vulnerability resides in the File Transmission component of Oracle Payments, part of the Oracle E-Business Suite. An attacker requires only network reachability over HTTP and a low-privileged account to exploit it. Attack complexity is low, and no user interaction is required. Successful exploitation grants unauthorized read access to all Oracle Payments accessible data and enables a partial denial of service. Confidentiality impact is high, while availability impact is low. Integrity is not affected.

Root Cause

The issue is classified as [CWE-200] Information Exposure. The File Transmission component discloses sensitive payment-related data to actors who should not have access to it. Oracle has not published detailed technical specifics beyond the July 2026 Critical Patch Update advisory. Payment file transmission workflows typically process sensitive financial records, account identifiers, and transaction metadata, making information exposure impactful for regulated environments.

Attack Vector

The attack vector is network-based over HTTP. An authenticated attacker with low privileges sends crafted HTTP requests to the Oracle Payments File Transmission interface. No victim interaction is required. Because the scope is unchanged, exploitation is confined to Oracle Payments, but all data accessible to that component can be exposed. The vulnerability can also be leveraged to induce a partial denial of service against Oracle Payments functionality.

See the Oracle Security Alert July 2026 for authoritative technical details.

Detection Methods for CVE-2026-60176

Indicators of Compromise

Unexpected HTTP requests targeting Oracle Payments File Transmission endpoints from low-privileged accounts.
Anomalous volumes of outbound payment data reads or file retrievals from Oracle E-Business Suite servers.
Repeated malformed or unusually crafted requests to Oracle Payments URLs that correlate with error responses or transient service degradation.

Detection Strategies

Review Oracle E-Business Suite HTTP access logs for File Transmission endpoint access originating from accounts that do not normally interact with Oracle Payments.
Correlate application-tier and database audit logs to identify user sessions that read large volumes of payments data within short time windows.
Alert on Oracle Payments service errors or partial outages that coincide with authenticated HTTP traffic from unexpected source addresses.

Monitoring Recommendations

Enable and retain Oracle E-Business Suite audit logs for Oracle Payments modules and forward them to a central SIEM.
Baseline normal request patterns for File Transmission endpoints and monitor deviations in request rate, source, or payload structure.
Track authentication events for Oracle E-Business Suite low-privileged accounts and flag lateral access into Oracle Payments components.

How to Mitigate CVE-2026-60176

Immediate Actions Required

Apply the July 2026 Oracle Critical Patch Update fixes for Oracle E-Business Suite Oracle Payments on all affected 12.2.3 through 12.2.15 deployments.
Inventory Oracle Payments instances and confirm patch status against Oracle's advisory before returning them to production traffic.
Restrict network reachability of Oracle E-Business Suite HTTP interfaces to trusted internal networks and VPN users only.

Patch Information

Oracle addressed CVE-2026-60176 in the Oracle Security Alert July 2026 Critical Patch Update. Administrators should download the applicable patches for Oracle E-Business Suite 12.2.3 through 12.2.15, review the Oracle patch readme, and apply the update in a maintenance window following Oracle's documented procedure. Verify the patch inventory with adop or the OPatch utility after application.

Workarounds

Limit access to Oracle Payments File Transmission endpoints using web-tier access controls and network segmentation until patches are applied.
Review and tighten role and responsibility assignments in Oracle E-Business Suite to reduce the population of low-privileged accounts that can reach Oracle Payments.
Increase logging verbosity on the Oracle HTTP Server and Oracle Payments modules to detect exploitation attempts prior to patch deployment.
