CVE-2026-46952: Oracle Quality Privilege Escalation Flaw

CVE-2026-46952 Overview

CVE-2026-46952 is a high-severity vulnerability in the Oracle Quality product of Oracle E-Business Suite, specifically within 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 this vulnerability without user interaction. Successful exploitation results in full takeover of Oracle Quality, impacting confidentiality, integrity, and availability. The vulnerability is mapped to CWE-269: Improper Privilege Management.

Critical Impact
Authenticated attackers can fully compromise Oracle Quality over the network using HTTP, leading to complete takeover of the product and exposure of sensitive enterprise quality management data.

Affected Products

Oracle E-Business Suite — Oracle Quality versions 12.2.3 through 12.2.15
Oracle Quality Internal Operations component
Oracle E-Business Suite deployments exposing Quality module HTTP interfaces

Technical Details for CVE-2026-46952

Vulnerability Analysis

The vulnerability resides in the Internal Operations component of Oracle Quality, part of Oracle E-Business Suite. Oracle Quality manages enterprise quality data collection, reporting, and process control within manufacturing and supply chain operations. The flaw allows a low-privileged authenticated user to escalate access and take over the Oracle Quality product entirely. The attack is delivered over HTTP and requires no user interaction. Oracle classifies the issue as easily exploitable, meaning weaponization does not require specialized conditions or chained primitives.

Root Cause

The weakness is categorized under CWE-269: Improper Privilege Management. Oracle Quality does not properly enforce privilege boundaries within the Internal Operations component. A user with minimal application-level credentials can perform operations reserved for higher-privileged roles. This control gap allows the attacker to manipulate application state, data, and configuration outside their authorization scope.

Attack Vector

The attack vector is network-based. An authenticated attacker sends crafted HTTP requests to the Oracle Quality endpoints exposed by the Internal Operations component. Because the scope is unchanged but confidentiality, integrity, and availability impacts are all high, successful requests grant the attacker control equivalent to a privileged Quality user. Oracle has not published technical exploitation details. See the Oracle Critical Patch Update June 2026 Security Alert for vendor guidance.

No verified proof-of-concept code is publicly available for CVE-2026-46952.

Detection Methods for CVE-2026-46952

Indicators of Compromise

Unexpected HTTP requests to Oracle Quality Internal Operations endpoints from low-privileged user sessions.
Anomalous privilege use or role transitions in Oracle E-Business Suite audit logs tied to the Quality module.
Unusual modification of Oracle Quality configuration, collection plans, or specification records by non-administrator accounts.

Detection Strategies

Enable Oracle E-Business Suite Sign-On Audit and Page Access Tracking to log access to Quality module URLs.
Correlate web tier access logs (access_log from Oracle HTTP Server) with database audit records for Quality schema tables.
Alert on HTTP requests to Internal Operations functions originating from accounts that lack the corresponding Quality responsibility.

Monitoring Recommendations

Monitor FND_LOGINS, FND_LOGIN_RESPONSIBILITIES, and Quality schema audit trails for anomalous activity.
Baseline normal request patterns to Oracle Quality and alert on deviations in request volume, source IP, or session role.
Forward Oracle E-Business Suite application, middleware, and database logs to a centralized SIEM for cross-source correlation.

How to Mitigate CVE-2026-46952

Immediate Actions Required

Apply the Oracle Critical Patch Update from June 2026 to all Oracle E-Business Suite environments running Quality 12.2.3-12.2.15.
Inventory all Oracle E-Business Suite instances and identify those exposing Oracle Quality to internal or external HTTP traffic.
Review and tighten Oracle Quality responsibilities and user role assignments to enforce least privilege.
Restrict network access to Oracle E-Business Suite web entry points so only authorized users and segments can reach the Quality module.

Patch Information

Oracle addressed CVE-2026-46952 in the Oracle Critical Patch Update Advisory - June 2026. Administrators should apply the patches listed in that advisory for Oracle E-Business Suite versions 12.2.3 through 12.2.15. Oracle recommends applying Critical Patch Updates as soon as possible because exploit code for Oracle vulnerabilities frequently appears after patch release.

Workarounds

No vendor-supplied workaround is documented; patching is the only complete remediation.
As a temporary control, restrict HTTP access to Oracle Quality Internal Operations endpoints using network ACLs or a web application firewall.
Reduce the number of users with active Oracle Quality responsibilities until patching is complete.

bash

# Example: restrict access to Oracle E-Business Suite Quality endpoints at the web tier
# Add to Oracle HTTP Server httpd.conf or a mod_security rule set
<LocationMatch "/OA_HTML/.*Quality.*">
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
</LocationMatch>
