CVE-2026-46867 Overview
CVE-2026-46867 affects the Oracle Enterprise Manager Base Platform within the Extensibility Framework component. The vulnerability impacts supported versions 13.5 and 24.1. An authenticated attacker with high privileges and network access over HTTPS can compromise the platform. Successful exploitation results in full takeover of the Oracle Enterprise Manager Base Platform, affecting confidentiality, integrity, and availability. Oracle addressed the issue in its June 2026 Critical Patch Update.
Critical Impact
Successful exploitation leads to complete takeover of Oracle Enterprise Manager Base Platform, granting attackers control over managed database and middleware assets.

Technical Details for CVE-2026-46867
Vulnerability Analysis
The flaw resides in the Extensibility Framework of Oracle Enterprise Manager Base Platform. This component handles plug-in management and custom monitoring extensions across managed targets. The vulnerability maps to [CWE-269] Improper Privilege Management, indicating that authenticated high-privileged users can escalate or abuse authority beyond their intended scope. Oracle classifies the issue as easily exploitable once the attacker holds valid high-privilege credentials. Successful exploitation yields confidentiality, integrity, and availability impacts equivalent to full product takeover.
Root Cause
The Extensibility Framework does not enforce sufficient privilege boundaries on certain administrative operations. Privilege validation gaps in this subsystem allow a high-privileged authenticated user to perform actions reserved for the platform itself. Because Enterprise Manager centrally administers Oracle databases, Fusion Middleware, and engineered systems, abuse of these operations grants control over the broader managed estate.
Attack Vector
The attack proceeds over the network via HTTPS to the Enterprise Manager console or its management endpoints. The attacker must first authenticate with high privileges, such as an Enterprise Manager administrator role. After authentication, the adversary issues crafted requests to the Extensibility Framework component to trigger the unauthorized action. User interaction is not required, and the scope remains unchanged. No public proof-of-concept exploit code is available at the time of publication.
No verified exploit code is publicly available. Refer to the Oracle Security Alert for vendor-supplied technical details.
Detection Methods for CVE-2026-46867
Indicators of Compromise
- Unexpected modifications to Enterprise Manager plug-ins, metric extensions, or management agents originating from administrative accounts.
- New or altered Enterprise Manager jobs, named credentials, or monitoring templates created outside change-control windows.
- HTTPS requests to Extensibility Framework endpoints from unusual source IP addresses or during non-business hours.
Detection Strategies
- Audit Enterprise Manager repository tables (SYSMAN.MGMT_AUDIT_MASTER, MGMT$AUDIT_LOG) for privileged operations against extensibility objects.
- Correlate Oracle HTTP Server access logs for the OMS console with administrator session activity to identify deviations from baseline.
- Monitor for privilege escalation patterns where existing administrative users invoke rarely used Extensibility Framework functions.
Monitoring Recommendations
- Enable Enterprise Manager auditing for all administrator and SUPER_USER role actions and forward logs to a centralized SIEM.
- Alert on changes to repository security configuration, named credentials, and plug-in lifecycle events.
- Track failed and successful logins for high-privilege accounts and review HTTPS request patterns to /em/ URIs.
How to Mitigate CVE-2026-46867
Immediate Actions Required
- Apply the Oracle Critical Patch Update from June 2026 to all Enterprise Manager Base Platform 13.5 and 24.1 deployments.
- Inventory all administrator and SUPER_USER accounts and remove unused high-privilege access.
- Rotate credentials for Enterprise Manager administrators and named credentials stored in the repository.
Patch Information
Oracle published the fix in the June 2026 Critical Patch Update. Administrators should follow the Oracle patch readme to apply the corresponding OMS-side patch and restart the Oracle Management Service. Verify patch level using emctl status oms -details and Oracle's OPatch lsinventory output.
Workarounds
- Restrict network access to the Enterprise Manager console to dedicated management subnets and jump hosts.
- Enforce multi-factor authentication for all Enterprise Manager administrator accounts to reduce credential abuse risk.
- Reduce the number of accounts granted the EM_ALL_ADMINISTRATOR or SUPER_USER roles and review privilege assignments quarterly.
