CVE-2026-83401 · Severity: medium · CVSS 6.1 · Published 2026-10-20

Oracle Identity Manager is an identity and access management system used to manage user accounts and permissions across enterprise applications. A vulnerability in its Legacy UI allows attackers to trick authenticated users into making unauthorized changes to user data or accessing sensitive information. An attacker could exploit this by sending a crafted link to an administrator, potentially leading to unauthorized account modifications or data exposure.

## Technical details

An unauthenticated network attacker can exploit a cross-site request forgery (CSRF) vulnerability in the OIM Legacy UI component via HTTP. The vulnerability requires user interaction from a person other than the attacker (e.g., a user clicks a malicious link), and affects the confidentiality and integrity of Identity Manager data while potentially impacting other connected systems. Successful exploitation results in unauthorized read access to a subset of Identity Manager data and unauthorized update, insert, or delete operations.
