"The 12.2.1.4.0 and 14.1.2.1.0 versions of Access Manager installed on the remote host are affected by multiple
vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the Oracle Access Manager product of Oracle Fusion Middleware (component: Authentication
    Engine). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.1.0. Easily exploitable
    vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Access
    Manager. While the vulnerability is in Oracle Access Manager, 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 Access Manager accessible data as well as
    unauthorized access to critical data or complete access to all Oracle Access Manager accessible data.
