CVE-2026-83344 Overview
CVE-2026-83344 affects the Oracle Identity Manager Connector product within Oracle Fusion Middleware. The flaw resides in the Database Application Table component and impacts supported versions 12.2.1.4.0 and 14.1.2.1.0. An attacker with high privileges and network access via HTTP can exploit the weakness to fully compromise the connector. Successful exploitation leads to takeover of the Oracle Identity Manager Connector, impacting confidentiality, integrity, and availability. The issue maps to [CWE-269: Improper Privilege Management].
Critical Impact
Successful exploitation results in complete takeover of the Oracle Identity Manager Connector, compromising identity provisioning workflows across integrated enterprise systems.
Affected Products
- Oracle Identity Manager Connector 12.2.1.4.0
- Oracle Identity Manager Connector 14.1.2.1.0
- Oracle Fusion Middleware (Database Application Table component)

Technical Details for CVE-2026-83344
Vulnerability Analysis
The vulnerability exists in the Database Application Table component of the Oracle Identity Manager Connector. This connector synchronizes identity data between Oracle Identity Manager and downstream database targets. Improper privilege management within the component allows an authenticated attacker holding high privileges to escalate control over the entire connector instance.
Successful exploitation grants the attacker administrative control over identity provisioning flows. Because the connector brokers account creation, modification, and deletion across integrated systems, compromise can cascade into downstream applications relying on it for identity governance.
Root Cause
The root cause is improper privilege management [CWE-269] within the Database Application Table component. Privilege boundaries between authenticated users and administrative connector functions are not enforced correctly, enabling a high-privileged actor to perform actions outside their intended authorization scope.
Attack Vector
The attack requires network access over HTTP and valid high-privileged credentials. No user interaction is needed, and the attack complexity is low. An attacker sends crafted HTTP requests to the connector interface to trigger the privilege management flaw and gain full control. No public exploit code or proof-of-concept has been published, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. See the Oracle Security Alert CSPUSEP2026 for vendor technical context.
Detection Methods for CVE-2026-83344
Indicators of Compromise
- Unexpected administrative HTTP requests to Oracle Identity Manager Connector endpoints originating from accounts that do not normally perform such actions.
- Anomalous modifications to Database Application Table configurations or provisioning rules.
- New or altered service accounts created via the connector without a corresponding change request.
Detection Strategies
- Correlate authentication events for privileged Oracle Identity Manager accounts with connector configuration changes to identify misuse patterns.
- Enable and review Oracle Fusion Middleware audit logs for Database Application Table operations invoked by non-standard users or from unusual source addresses.
- Baseline normal HTTP request volume and endpoints for the connector, and alert on deviations from that baseline.
Monitoring Recommendations
- Forward Oracle Identity Manager and WebLogic audit logs to a centralized SIEM for correlation and long-term retention.
- Monitor privileged session activity against the connector, including login times, source IPs, and executed operations.
- Track downstream provisioning targets for unexpected account creation, permission changes, or role assignments that could indicate connector abuse.
How to Mitigate CVE-2026-83344
Immediate Actions Required
- Apply the fixes referenced in the Oracle Security Alert CSPUSEP2026 to affected Oracle Identity Manager Connector installations.
- Inventory all deployments running versions 12.2.1.4.0 and 14.1.2.1.0 and prioritize patching internet-reachable instances first.
- Rotate credentials for all high-privileged Oracle Identity Manager accounts and review recent administrative activity for signs of misuse.
Patch Information
Oracle has published remediation guidance in the Oracle Security Alert CSPUSEP2026. Administrators should consult the alert for version-specific patch identifiers and installation instructions applicable to their Oracle Fusion Middleware environment.
Workarounds
- Restrict HTTP access to the Oracle Identity Manager Connector to trusted management networks and jump hosts only.
- Enforce least privilege for connector administrative roles and remove standing high-privileged access where possible.
- Require multi-factor authentication for all accounts capable of interacting with the connector administrative interfaces.
# Example: restrict connector access at the network layer using iptables
iptables -A INPUT -p tcp --dport 14000 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 14000 -j DROP
