CVE-2026-46928 Overview
CVE-2026-46928 is a privilege management vulnerability [CWE-269] in the Oracle Spares Management product of Oracle E-Business Suite. The flaw resides in the Internal Operations component and affects supported versions 12.2.3 through 12.2.15. A low-privileged attacker with network access via HTTPS can exploit the issue without user interaction. Successful exploitation results in full takeover of Oracle Spares Management, with high impact to confidentiality, integrity, and availability.
Critical Impact
An authenticated attacker holding minimal privileges can take complete control of Oracle Spares Management over the network, compromising all data managed by the application.
Affected Products

Technical Details for CVE-2026-46928
Vulnerability Analysis
The vulnerability sits in the Internal Operations component of Oracle Spares Management, part of the broader Oracle E-Business Suite stack. Oracle's advisory describes the issue as easily exploitable by a low-privileged attacker over HTTPS. The CWE-269 classification points to improper privilege management, where an account with limited entitlements can perform actions reserved for higher-privileged roles. Successful exploitation leads to full takeover of the Spares Management application, exposing all stored records and workflows.
The Exploit Prediction Scoring System (EPSS) currently rates the probability of exploitation at 0.389% (percentile 30.579). No public proof-of-concept code or in-the-wild exploitation has been reported at this time.
Root Cause
The root cause is improper enforcement of privilege boundaries within the Internal Operations component [CWE-269]. The application fails to validate that the authenticated user holds the required role before executing privileged operations. As a result, requests issued by a standard application user are processed as if they originated from a higher-trust principal.
Attack Vector
The attack is network-based and delivered over HTTPS to the Oracle E-Business Suite front-end. The attacker must hold a valid low-privileged account on the target system. No user interaction is required, and the scope remains unchanged. Once authenticated, the attacker issues crafted requests to the vulnerable Internal Operations endpoints to escalate privileges and assume control of Oracle Spares Management.
No verified exploit code is publicly available. Refer to the Oracle Security Alert for vendor-supplied technical context.
Detection Methods for CVE-2026-46928
Indicators of Compromise
- Unexpected privileged actions in Spares Management audit logs originating from accounts that historically only performed read or standard operations.
- HTTPS requests to Internal Operations endpoints from internal users whose role assignments do not include those functions.
- New or modified administrative records, parts catalogs, or workflow configurations created outside of change-window timeframes.
Detection Strategies
- Correlate Oracle E-Business Suite application logs with Single Sign-On and database audit trails to flag actions performed beyond a user's assigned responsibilities.
- Baseline normal request patterns to Spares Management endpoints and alert on deviations such as direct invocations of Internal Operations URLs by non-administrative roles.
- Review FND_LOGINS and FND_UNSUCCESSFUL_LOGINS tables alongside concurrent request history for anomalous escalations.
Monitoring Recommendations
- Enable Oracle E-Business Suite Sign-On Audit at the FORM level and forward records to a centralized SIEM for retention and search.
- Monitor WAF and reverse proxy logs for repeated requests to Spares Management Internal Operations URIs from a single session.
- Alert on changes to responsibility assignments (FND_USER_RESP_GROUPS) that grant Spares Management privileges outside approved change tickets.
How to Mitigate CVE-2026-46928
Immediate Actions Required
- Apply the Oracle Critical Patch Update referenced in the Oracle Security Alert to all Oracle E-Business Suite instances running Spares Management versions 12.2.3 through 12.2.15.
- Inventory all accounts with access to Spares Management and remove entitlements that are not required for current job duties.
- Restrict network reachability to the Oracle E-Business Suite front-end so only trusted corporate networks and VPN ranges can connect over HTTPS.
Patch Information
Oracle addresses CVE-2026-46928 in the June 2026 Critical Security Patch Update. Administrators should apply the corresponding Spares Management patch to all affected versions in the 12.2.x line. Patch availability, prerequisites, and application order are documented in the Oracle Security Alert.
Workarounds
- If patching cannot be completed immediately, disable the Spares Management responsibility for all non-essential users until the fix is deployed.
- Place the Oracle E-Business Suite environment behind a web application firewall that enforces role-based URL access controls for Internal Operations endpoints.
- Increase audit logging verbosity for Spares Management functions and require step-up authentication for privileged operations through Oracle Access Manager or an equivalent identity broker.
