Summary
CVE-2026-60721 is a critical, easily exploitable vulnerability in the OIM Legacy UI component of Oracle Identity Manager, part of Oracle Fusion Middleware. The flaw allows a remote, unauthenticated attacker with only network access via HTTP to fully compromise the affected system, impacting confidentiality, integrity, and availability. Oracle disclosed the issue with a CVSS v3.1 base score of 9.8 (Critical) as part of its August 2026 Critical Patch Update.
Technical details
- Root cause: The vulnerability resides in the OIM Legacy UI component of Oracle Identity Manager; Oracle’s advisory characterizes it as "easily exploitable" over HTTP without any authentication.
- Trigger conditions: An attacker only needs network-level HTTP access to the exposed Oracle Identity Manager instance — no valid credentials or user interaction are required.
- Attack vector: Network (AV:N), with low attack complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N) required, making it exploitable directly over the internet or internal network where the service is reachable.
- Impact: Successful exploitation results in complete compromise of the Oracle Identity Manager system, with high impact to confidentiality, integrity, and availability (C:H/I:H/A:H) — consistent with unauthenticated remote code execution or full system takeover.
- At the time of this writing (day of public disclosure), no public proof-of-concept exploit code or third-party technical writeup has been identified beyond the official Oracle/CVE record; details are limited to what Oracle and the CVE Program have published.
Affected software
- Oracle Identity Manager (Oracle Fusion Middleware) — version 12.2.1.4.0
- Oracle Identity Manager (Oracle Fusion Middleware) — version 14.1.2.1.0
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the fix provided in Oracle’s August 2026 Critical Patch Update for Oracle Identity Manager versions 12.2.1.4.0 and 14.1.2.1.0. Organizations should follow Oracle’s official Critical Patch Update guidance to identify and install the correct patch for their deployed version.
- If patching cannot be applied immediately:
- Restrict network exposure of Oracle Identity Manager, particularly the OIM Legacy UI component, by limiting access to trusted internal networks and blocking direct internet exposure.
- Place the affected service behind a web application firewall (WAF) or reverse proxy with strict access controls as a compensating control until the patch is applied.
- Monitor HTTP access logs for the OIM Legacy UI endpoints for anomalous or unauthenticated requests.
- Prioritize patching given the unauthenticated, network-exploitable nature of this vulnerability and its critical CVSS score.
