CVE-2026-46951: Oracle Quality Privilege Escalation Flaw

CVE-2026-46951 Overview

CVE-2026-46951 is a high-severity vulnerability in the Oracle Quality product of Oracle E-Business Suite, specifically in the Internal Operations component. Affected versions span Oracle Quality 12.2.3 through 12.2.15. A low-privileged attacker with network access over HTTP can exploit this flaw without user interaction. Successful exploitation results in full takeover of the Oracle Quality application, impacting confidentiality, integrity, and availability. The weakness is classified under [CWE-269] Improper Privilege Management.

Critical Impact
Authenticated attackers can remotely compromise Oracle Quality and take over the application, accessing or modifying sensitive manufacturing and quality data.

Affected Products

Oracle E-Business Suite — Oracle Quality 12.2.3
Oracle E-Business Suite — Oracle Quality versions 12.2.4 through 12.2.14

Technical Details for CVE-2026-46951

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Quality, a module of Oracle E-Business Suite used to capture and analyze manufacturing quality data. An attacker with an authenticated low-privileged account can send crafted HTTP requests to the affected endpoints and elevate their effective privileges within the application. The flaw maps to [CWE-269] Improper Privilege Management, indicating that the application fails to correctly enforce the privilege boundaries assigned to a given user role. Because no user interaction is required and the attack complexity is low, exploitation is straightforward once an attacker has any valid session against the E-Business Suite instance.

Root Cause

The root cause is improper privilege management within the Internal Operations functionality of Oracle Quality. Authorization checks are insufficient to prevent low-privileged users from invoking actions reserved for higher-privileged roles. As a result, a single authenticated session can escalate to a level capable of compromising the confidentiality, integrity, and availability of the Quality application data and workflows.

Attack Vector

Exploitation occurs over the network via HTTP against an exposed Oracle E-Business Suite deployment. The attacker requires only low-level credentials, which can often be obtained through default accounts, phishing, or lateral movement from other compromised systems. There is no public proof-of-concept code at this time, and the EPSS probability remains low, but the combination of network reach and minimal privilege requirements makes prioritized patching important.

No verified exploitation code is publicly available. Refer to the Oracle Security Alert: CSPU Jun 2026 for vendor-specific technical context.

Detection Methods for CVE-2026-46951

Indicators of Compromise

Unexpected HTTP POST or GET requests to Oracle Quality Internal Operations endpoints from low-privileged user sessions.
Audit log entries showing privilege-sensitive actions performed by accounts that do not normally hold administrative roles.
Creation or modification of Oracle Quality configuration records outside of change-window activity.
Authentication anomalies such as logins from new geolocations or atypical hours immediately preceding privileged actions.

Detection Strategies

Enable and review Oracle E-Business Suite Sign-On Audit and Page Access Tracking to correlate user identity with Quality module activity.
Deploy web application firewall rules to inspect HTTP requests targeting Oracle Quality URLs and flag anomalous parameter patterns.
Baseline normal user-to-function mappings and alert when low-privileged accounts invoke Internal Operations functions.

Monitoring Recommendations

Forward Oracle E-Business Suite application and database audit logs to a centralized SIEM for correlation against authentication telemetry.
Monitor FND_USER and FND_RESPONSIBILITY tables for unauthorized changes to user roles and responsibilities.
Track outbound connections from the Oracle application tier that may indicate post-compromise activity.

How to Mitigate CVE-2026-46951

Immediate Actions Required

Apply the patches provided in the Oracle Security Alert: CSPU Jun 2026 advisory to all affected Oracle Quality 12.2.3 through 12.2.15 instances.
Inventory Oracle E-Business Suite deployments and identify any internet-exposed instances for priority patching.
Review Oracle Quality user accounts and remove unused or default low-privileged accounts that could be abused.
Rotate credentials for accounts with access to the Quality module following patch deployment.

Patch Information

Oracle has released fixes through the June 2026 Critical Security Patch Update. Administrators should follow the patching guidance in the Oracle Security Alert: CSPU Jun 2026, apply patches to all instances of Oracle E-Business Suite Oracle Quality 12.2.3 through 12.2.15, and validate the patch in a non-production environment before production rollout.

Workarounds

Restrict network access to Oracle E-Business Suite to trusted internal networks and VPN users only.
Enforce strong multi-factor authentication on all Oracle E-Business Suite accounts to reduce the risk of low-privileged credential abuse.
Temporarily disable or restrict access to the Oracle Quality Internal Operations functionality where business processes allow until patches are applied.

bash

# Configuration example: restrict access to Oracle E-Business Suite at the network edge
# Replace 10.0.0.0/8 with your trusted internal network range
iptables -A INPUT -p tcp --dport 8000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 8000 -j DROP
