WHAT IT DOES

What sendTwoFactorCodeForLoginUsingMethodWithId does on Fusionauth

AI agents invoke sendTwoFactorCodeForLoginUsingMethodWithId to trigger actions in Fusionauth. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why sendTwoFactorCodeForLoginUsingMethodWithId is rated High

This tool triggers an external operation — sending a 2FA code (likely via SMS, email, or authenticator channel) to a user. It is not a simple read or write of stored data; it actively initiates a side-effecting delivery action. Misuse could be used to spam users with authentication codes or facilitate account takeover attempts, giving it medium severity.
