CVE-2026-91492 in Identity Manager Connector
Summary
by MITRE • 10/21/2026
Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: SAP ERP+). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Identity Manager Connector. While the vulnerability is in Oracle Identity Manager Connector, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Identity Manager Connector accessible data as well as unauthorized access to critical data or complete access to all Oracle Identity Manager Connector accessible data. CVSS 3.1 Base Score 8.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N).

The identified vulnerability resides within the Oracle Identity Manager Connector, specifically targeting the integration component for SAP ERP+ systems as part of the broader Oracle Fusion Middleware suite. This security flaw affects specific legacy and current versions including 12.2.1.4.0 and 14.1.2.1.0. The core technical nature of this vulnerability is characterized by a lack of proper authentication enforcement or validation within the HTTP interface exposed by the connector. Although the description notes that exploitation is difficult, likely due to complex input requirements or specific environmental conditions needed for successful execution, it remains accessible to unauthenticated attackers who possess network connectivity to the affected service via standard HTTP protocols. This indicates a fundamental failure in access control mechanisms where sensitive administrative functions are not adequately restricted to authorized personnel only.
The operational impact of this vulnerability is severe due to its high confidentiality and integrity ratings on the CVSS 3.1 scale, which assigns it a base score of 8.7. Successful exploitation allows an attacker to perform unauthorized creation, deletion, or modification of critical data within the Oracle Identity Manager Connector environment. Furthermore, it grants complete access to all data accessible by the connector, effectively bypassing security boundaries designed to protect sensitive identity and provisioning information. The scope change aspect is particularly concerning because while the flaw originates in the connector component, the consequences ripple through to other integrated products. This means that compromising this single entry point can lead to a broader compromise of the entire Oracle Fusion Middleware ecosystem dependent on accurate identity management data from SAP ERP systems.
From an industry standard perspective, this vulnerability aligns with CWE-287 Improper Authentication and CWE-918 Server-Side Request Forgery if the HTTP access involves proxying requests, though primarily it represents a critical failure in Access Control (CWE-862). In terms of adversary behavior mapping to MITRE ATT&CK, this vulnerability facilitates initial access through network services that lack proper authentication checks. The ability to modify and delete data maps directly to techniques involving persistence or impact via data manipulation, such as Data Manipulation for Impact or Account Modification within the Identity Management framework. Attackers could leverage this flaw to establish persistent backdoors by creating unauthorized user accounts with elevated privileges, thereby maintaining long-term access even if other security controls are tightened later.
Mitigation strategies must prioritize immediate isolation and patching given the high severity score. Organizations running affected versions should apply the latest available patches from Oracle that address these specific authentication flaws in the SAP ERP+ connector. Until patches can be applied, network-level mitigations such as restricting HTTP access to the connector interface via firewall rules or web application firewalls are essential. Access control lists should be configured to allow connections only from trusted IP addresses associated with legitimate administrative workstations and integration endpoints. Additionally, implementing strict input validation on any exposed interfaces and enabling comprehensive logging for authentication failures can aid in early detection of exploitation attempts. Regular audits of identity management configurations and review of access logs for anomalous creation or deletion activities are recommended to detect potential compromise resulting from this vulnerability.
