Assigner: Okta
Reserved: 24.08.2026 Published: 08.09.2026 Updated: 08.09.2026

The Okta Hyperdrive Agent writes the decoded SAML bearer assertion to a local application log file at the default log level on every successful MFA completion. This insertion of sensitive information into the log file makes a live authentication credential readable by any local user with access to the log file.
