CVE-2026-47007: Oracle Pricing Design Center Auth Bypass

CVE-2026-47007 Overview

CVE-2026-47007 affects the Oracle Communications Pricing Design Center (PDC) product, specifically the On-premise Deployment component. The flaw is classified as an improper access control weakness [CWE-284] and allows a low-privileged attacker with logon access to the underlying infrastructure to compromise the application. Successful exploitation results in unauthorized access to critical data and unauthorized modification of a subset of data. Because the vulnerability has a scope change, exploitation can extend impact to additional products beyond PDC itself. Oracle disclosed the issue in the July 2026 Critical Patch Update advisory.

Critical Impact
Local low-privileged attackers can obtain full read access to PDC data and modify a subset of data, with scope-changing impact to adjacent Oracle Communications products.

Affected Products

Oracle Communications Pricing Design Center 15.0.0.0.0
Oracle Communications Pricing Design Center 15.0.1.0.0
Oracle Communications Pricing Design Center 15.1.0.0.0
Oracle Communications Pricing Design Center 15.2.0.0.0

Technical Details for CVE-2026-47007

Vulnerability Analysis

The vulnerability resides in the On-premise Deployment component of Oracle Communications Pricing Design Center. An authenticated user who can log on to the infrastructure hosting PDC can leverage improper access control to reach data and functionality that should be restricted. The scope-change property indicates that the vulnerable component and the impacted component fall under different security authorities. Exploitation therefore affects not only PDC data but potentially data managed by adjacent Oracle Communications products that trust the PDC security context.

Confidentiality impact is rated high because an attacker can obtain complete access to all data reachable by the PDC service. Integrity impact is limited but real, allowing unauthorized insert, update, or delete of a subset of records. Availability is not affected. Oracle characterizes the vulnerability as easily exploitable, meaning no unusual conditions are required once the attacker has local logon.

Root Cause

The root cause is improper access control [CWE-284] within the On-premise Deployment component. Authorization checks fail to correctly validate whether a low-privileged principal is entitled to invoke privileged data operations or cross trust boundaries into adjacent product data stores.

Attack Vector

The attack vector is local. The attacker must have valid credentials and logon access to the server where PDC executes. From that position, the attacker interacts with PDC interfaces to read data and perform limited write operations that the access control layer should have denied. No user interaction is required. Oracle has not published proof-of-concept code, and no public exploit is available at time of writing. See the Oracle July 2026 Security Alert for vendor technical details.

Detection Methods for CVE-2026-47007

Indicators of Compromise

Unexpected data reads or exports from PDC by accounts that do not normally perform administrative queries
Insert, update, or delete operations on PDC tables originating from low-privileged service or user accounts
Cross-product data access patterns where PDC processes reach into adjacent Oracle Communications datastores unexpectedly

Detection Strategies

Enable and centralize PDC audit logging, focusing on authorization decisions and data-access events
Correlate operating system logon events on PDC hosts with subsequent application-level actions to spot privilege abuse
Baseline normal query and mutation patterns per role and alert on deviations, particularly bulk data reads by non-admin accounts

Monitoring Recommendations

Forward PDC application, database, and host logs to a centralized analytics platform for retention and correlation
Monitor Oracle CPU advisory channels for updates to the July 2026 alert and revised affected version lists
Track EPSS scoring for CVE-2026-47007 over time to detect increases that suggest emerging exploitation

How to Mitigate CVE-2026-47007

Immediate Actions Required

Apply the July 2026 Critical Patch Update from Oracle to all PDC 15.0.0.0.0, 15.0.1.0.0, 15.1.0.0.0, and 15.2.0.0.0 deployments
Inventory all hosts running Oracle Communications Pricing Design Center and confirm patch status
Review and reduce the population of accounts with interactive or service logon rights to PDC infrastructure

Patch Information

Oracle released fixes as part of the July 2026 Critical Patch Update. Administrators should download and apply the patches referenced in the Oracle July 2026 Security Alert for each affected PDC version. No supported workaround from Oracle removes the vulnerability without patching.

Workarounds

Restrict logon to PDC servers to a minimal set of administrators using host-based access controls and jump hosts
Enforce strong authentication and session monitoring for any account able to reach PDC infrastructure
Segment PDC hosts and adjacent Oracle Communications systems on isolated network zones to limit scope-change impact

bash

# Example: restrict interactive logon on a Linux PDC host to a defined admin group
# /etc/security/access.conf
-:ALL EXCEPT pdc_admins root:ALL

# Audit successful and failed logons on the PDC host
auditctl -w /var/log/secure -p wa -k pdc_logon
