Bypassing 2FA using OpenID Misconfiguration
An OpenID relying party asks for authentication methods through the acr_values parameter, and the identity provider honours any method the client has enabled. Changing the request from one-time password to SMS let an attacker satisfy two-factor authentication with a throwaway SMS number, skipping the authenticator app step entirely.
