Does this matter?

Lower severity and a low EPSS score (0.10%). Track it; it rarely justifies an emergency change on its own.

Description

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.
