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

Summary

The Okta Hyperdrive agent plugin returns a success response without a signed SAML assertion when the organization's policy requires no MFA for a given user. The response contains only a bare boolean validation indicator with no cryptographic artifact, resulting in an unverifiable authentication verdict being delivered to the relying application.

Risk Assessment

Risk of unauthorized access to applications because the authentication verdict cannot be cryptographically verified, potentially allowing an attacker to impersonate a user.

Recommendation

Update Okta Hyperdrive to a patched version and enforce signed SAML assertions even when MFA is not required.
