CVE-2026-60959: Oracle SDP Auth Bypass Vulnerability

CVE-2026-60959 Overview

CVE-2026-60959 is a high-severity vulnerability in the Oracle SDP Number Portability product of Oracle E-Business Suite, specifically in 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 to compromise Oracle SDP Number Portability. Successful exploitation results in unauthorized creation, deletion, or modification of critical data, along with unauthorized read access to all accessible data within the product.

Critical Impact
An authenticated network attacker can compromise the confidentiality and integrity of all data accessible to Oracle SDP Number Portability across affected Oracle E-Business Suite deployments.

Technical Details for CVE-2026-60959

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle SDP Number Portability, part of the Oracle E-Business Suite. The attack requires only low privileges and no user interaction, making authenticated users on the network capable of triggering the flaw. The scope remains unchanged, but confidentiality and integrity impacts are both high. Availability is not affected, which suggests the flaw enables data access and manipulation rather than service disruption.

The EPSS score is 0.365% with a percentile ranking of 29.035, and no public exploit code has been observed at the time of publication.

Root Cause

Oracle has not disclosed detailed root cause information in the public advisory. Based on the CVSS metrics and the affected component, the vulnerability likely stems from insufficient authorization checks or improper input validation within HTTP-facing interfaces of the Internal Operations component. Refer to the Oracle Security Alert - July 2026 for further vendor-supplied technical details.

Attack Vector

Exploitation occurs over the network via HTTP against an Oracle E-Business Suite instance exposing the Oracle SDP Number Portability application. The attacker must hold valid low-privilege credentials to the application. Once authenticated, the attacker can issue crafted HTTP requests to abuse the vulnerable functionality and read or manipulate data outside the intended authorization boundary. No user interaction is required, and attack complexity is low.

See the Oracle Security Alert - July 2026 for vendor guidance on exposure and mitigation.

Detection Methods for CVE-2026-60959

Indicators of Compromise

Unexpected create, update, or delete operations against Oracle SDP Number Portability tables performed by low-privilege application accounts.
Anomalous HTTP requests to Internal Operations endpoints originating from user accounts that do not typically access these functions.
Unusual data exports or bulk read operations against Oracle SDP Number Portability accessible data.

Detection Strategies

Enable Oracle E-Business Suite audit logging on the SDP Number Portability schema and monitor for privilege-boundary violations.
Correlate HTTP access logs with application-level identity data to flag low-privilege sessions invoking Internal Operations URLs.
Baseline expected transaction volumes for the Number Portability workflows and alert on statistical deviations.

Monitoring Recommendations

Forward Oracle E-Business Suite application, database, and web-tier logs to a centralized analytics platform for correlation.
Track authentication events for accounts with access to SDP Number Portability and alert on off-hours or geographically unusual logins.
Monitor database change logs for unauthorized schema-level modifications following HTTP activity against Internal Operations endpoints.

How to Mitigate CVE-2026-60959

Immediate Actions Required

Apply the fixes distributed in the Oracle July 2026 Critical Patch Update to all Oracle E-Business Suite deployments running versions 12.2.3 through 12.2.15.
Inventory internet-exposed Oracle E-Business Suite instances and prioritize patching for those reachable from untrusted networks.
Review and reduce standing access to Oracle SDP Number Portability functionality, enforcing least privilege.
Rotate credentials for accounts with access to the affected component if compromise is suspected.

Patch Information

Oracle addressed CVE-2026-60959 as part of the July 2026 Critical Patch Update. Administrators should download and apply the relevant patches for Oracle E-Business Suite 12.2 per the vendor advisory. Full details are available in the Oracle Security Alert - July 2026.

Workarounds

Restrict HTTP access to the Oracle SDP Number Portability application to trusted internal networks or VPN users only.
Enforce web application firewall rules that limit access to Internal Operations endpoints based on source IP and authenticated role.
Disable Oracle SDP Number Portability functionality where it is not required until the patch can be applied.
