1th percentile - higher than 1% of all known CVEs

Summary

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.

Risk Assessment

The risk involves exposure of live authentication credentials to local users, which could enable unauthorized access to systems and data.

Recommendation

It is recommended to change the log level to avoid writing SAML assertions, and restrict access to log files. Also consider updating the Okta Hyperdrive agent to a patched version.
