Summary
CVE-2026-60727 is a critical vulnerability in the Legacy UI component of Oracle Identity Manager, part of Oracle Fusion Middleware. The flaw allows an unauthenticated, remote attacker with only network access via HTTP to fully compromise Oracle Identity Manager, resulting in complete loss of confidentiality, integrity, and availability. Oracle disclosed the issue in its August 2026 Critical Security Patch Update, and it carries the maximum practical CVSS v3.1 base score of 9.8 (Critical).
Technical details
- Root cause: A weakness in the Legacy UI component of Oracle Identity Manager that permits an attacker to bypass authentication controls and interact with functionality that should require valid credentials.
- Trigger conditions: The vulnerable code path is reachable over HTTP without any prior authentication, user interaction, or special network position.
- Attack vector: Network (AV:N) — exploitable remotely over HTTP against any internet- or network-exposed Oracle Identity Manager Legacy UI endpoint.
- Attack complexity: Low (AC:L) — no special conditions or timing are required to exploit the flaw.
- Privileges required / User interaction: None (PR:N / UI:N) — the attacker needs no account and no victim action.
- Impact: Successful exploitation results in complete compromise of Oracle Identity Manager, with high impact to confidentiality, integrity, and availability (C:H/I:H/A:H). Given Identity Manager’s role as an identity and access management platform, compromise can cascade into broader identity infrastructure risk (e.g., unauthorized account/privilege manipulation).
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 Security Patch Update for Oracle Identity Manager versions 12.2.1.4.0 and 14.1.2.1.0. Follow Oracle’s official patch application instructions for your specific deployment topology.
- If patching cannot be applied immediately: Restrict network access to the Oracle Identity Manager Legacy UI so it is not reachable from untrusted networks or the public internet; place it behind a properly configured firewall, VPN, or reverse proxy that limits access to trusted administrative sources only. Monitor access logs for the Legacy UI component for anomalous or unauthenticated requests.
- Prioritize this patch given the pre-authentication network attack vector and critical severity, and treat internet-facing Oracle Identity Manager instances as high risk until patched.
