Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle Identity Manager product of Oracle Fusion Middleware (component: OIM Legacy UI). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Identity Manager. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Identity Manager accessible data as well as unauthorized access to critical data or complete access to all Oracle Identity Manager accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
AnalysisAI
Data compromise in Oracle Identity Manager (OIM Legacy UI component) versions 12.2.1.4.0 and 14.1.2.1.0 allows a low-privileged, network-based attacker to read, create, delete, or modify all data accessible to the identity platform. The flaw is tracked in Oracle's July 2026 Critical Patch Update and carries a CVSS 3.1 score of 8.1 with high confidentiality and integrity impact. No public exploit has been identified at time of analysis, but the low attack complexity and network vector make it a strong patching priority for enterprise IAM deployments.
Technical ContextAI
Oracle Identity Manager is an enterprise identity-governance and access-provisioning platform within Oracle Fusion Middleware, managing user accounts, roles, and entitlements across connected systems. The vulnerable surface is the legacy OIM web UI, reached over HTTP. Oracle assigned no CWE; the vendor tag 'Authentication Bypass' combined with the CVSS PR:L metric indicates an authenticated low-privilege user can escalate their effective data authorization - accessing or altering records beyond their intended scope - pointing to a broken access-control / authorization-flaw class rather than a fully pre-authentication bypass. Because OIM is itself the authority for identity data, an integrity compromise here can cascade into unauthorized account and entitlement changes across downstream managed systems.
RemediationAI
Patch available per vendor advisory: apply the fixes bundled in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html) for the affected Oracle Identity Manager releases 12.2.1.4.0 and 14.1.2.1.0 - Oracle does not publish a standalone semantic fix version, so use the CPU patch identifiers listed in the advisory for your exact release. As compensating controls until patching, restrict network reachability of the OIM Legacy UI to trusted administrative networks or VPN, and where operationally feasible disable or block access to the legacy UI endpoints in favor of the current UI (trade-off: legacy integrations or admin workflows depending on it will break). Additionally tighten and audit low-privilege OIM role assignments and enable request/access logging to detect anomalous data reads or modifications; these do not remove the flaw but reduce the population of accounts that can reach it.
