## Technical details

A NULL pointer dereference vulnerability exists in the sendOTPEmail function in pkg/auth/local.go. The function dereferences a pointer obtained from an unchecked error path without validating that the pointer is non-nil, triggering a fatal panic. The vulnerable code path is triggered when an unauthenticated attacker sends a recovery request to the /api/auth/local/recover endpoint, causing the entire server process to terminate. No authentication is required and the attack requires only a single HTTP request. No patch information has been publicly disclosed.
