Exploitation Conditions

Exploitation requires the attacker to already hold high privileges within Oracle Identity Manager (CVSS PR:H) and network access to the Connectors and Connector Server component via SOAP; affected products are Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0. The primary limiting factor is the high-privilege prerequisite - this cannot be triggered by an unauthenticated or low-privileged remote attacker - while the scope change (S:C) means successful exploitation can extend impact beyond the connector into additional products. No user interaction is required and attack complexity is low once the privilege and SOAP-access conditions are met.

Impact

This is a genuine but conditionally-gated risk rather than a drop-everything emergency. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N, 8.7) shows network reachability over SOAP with low attack complexity and no user interaction, and a scope change that lets impact spill into additional products - all serious. However, PR:H is the decisive limiter: the attacker must already hold high privileges within the Oracle Identity Manager environment, so this is a privilege-abuse/lateral-movement-and-escalation issue, not an anonymous internet-facing takeover. No EPSS score, CISA KEV listing, or public POC is present in the provided data, so there is no public exploit identified at time of analysis and no evidence of active exploitation. Note a signal conflict worth verifying: the input Tags include 'Authentication Bypass,' which contradicts the PR:H vector and the description's 'high privileged attacker' language - the Oracle description does not describe an authentication bypass, so treat that tag as suspect and rely on the CVSS vector. Net: a real high-severity patch-priority item for organizations running affected Oracle IAM, but the high-privilege prerequisite makes mass, widespread exploitation unlikely absent a prior foothold.

Exploit ScenarioDerived

An attacker who has already obtained high-privileged credentials or a compromised privileged account on an Oracle Identity Manager deployment sends crafted SOAP requests over the network to the Connectors/Connector Server component. Because exploitation is low-complexity and triggers a scope change, the attacker can read, create, delete, or modify critical identity data and pivot to significantly impact additional connected products. No public exploit code is identified at time of analysis.

AnalysisAIv1 – Oct 20, 2026

High-privileged SOAP access to Oracle Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0 can be abused to read and modify critical connector data, with scope change extending impact to additional Oracle Fusion Middleware products. The flaw is easily exploitable once an attacker already holds high privileges in the product (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N, 8.7) and requires network reachability to the Connectors and Connector Server component; no public exploit was identified at time of analysis.

RemediationAI

Apply the Oracle Critical Patch Update October 2026 fix for Oracle Identity Manager Connector 12.2.1.4.0 and 14.1.2.1.0; the supplied data does not provide an exact fixed version number, so confirm the target version in the Oracle advisory at https://www.oracle.com/security-alerts/cpuoct2026.html. Until patched, restrict network access to the Connectors and Connector Server SOAP endpoints to trusted integration hosts and tightly limit and monitor accounts holding high privileges in Oracle Identity Manager, since exploitation requires PR:H; these controls reduce exposure but can break legitimate connector traffic and require maintaining an accurate allowlist. Prioritize patching where high-privileged users or broad SOAP reachability exist, and review connector-to-target-system permissions because scope change means impact can extend beyond the connector.

Technical ContextAI · show details

Oracle Identity Manager Connector is the integration component within Oracle Fusion Middleware that lets Oracle Identity Manager provision and reconcile accounts against connected target systems; the Connectors and Connector Server component exposes SOAP-based interfaces. The assessed CVSS vector indicates the issue is reachable over the network with low attack complexity and no user interaction, but requires the attacker to already possess high privileges (PR:H). Because scope is changed (S:C), compromise of the connector can affect resources beyond the connector itself, consistent with Oracle's note that attacks may significantly impact additional products. No CWE identifier was supplied, so the precise implementation flaw class cannot be confirmed from the available data.

DescriptionCVE.org

Vulnerability in the Oracle Identity Manager Connector product of Oracle Fusion Middleware (component: Connectors and Connector Server). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Easily exploitable vulnerability allows high privileged attacker with network access via SOAP 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:L/PR:H/UI:N/S:C/C:H/I:H/A:N).

Executive ViewAI

Why It Matters

Oracle Identity Manager Connector versions 12.2.1.4.0 and 14.1.2.1.0 contain a high-severity flaw that allows an authenticated attacker with high privileges to read and modify critical connector data, with scope change potentially affecting other Oracle Fusion Middleware products. Organizations running these versions face risks to identity data integrity and adjacent middleware, though exploitation requires existing high-privileged access and no public exploit has been identified at time of analysis. Leadership should prioritize interim access restrictions and monitoring until a vendor patch is released.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis; restrict network reachability to the Connectors and Connector Server component, enforce least privilege and review high-privileged accounts, and monitor SOAP access and connector data changes.
