Overview

Affected versions of this package are vulnerable to Missing Critical Step in Authentication via the OIDC authorize process. An attacker can gain unauthorized access to valid OIDC tokens by leveraging a session where only the password has been verified but the second authentication factor has not been completed. This allows the attacker to impersonate the victim and obtain access, provided they know the victim's password but not their TOTP secret. This is only exploitable if an OIDC client is configured and the attacker has obtained the user's password.
