data, resulting in a denial of service (DOS) attack. The new version includes Log4j 2.16.0 which fixes this issue by removing support for message lookup patterns and disabling JNDI functionality by default. </p><h3>Affected product and versions</h3><p>Okta On-Prem MFA Agent (formerly Okta RSA SecurID Agent) 1.4.6</p><h3>Resolution</h3><p>The vulnerability is fixed in Okta On-Prem MFA Agent (formerly Okta RSA SecurID Agent) version 1.4.7.
