Bug and impact
Public
POST /auth/forgot-passwordaccepted any truthyemailvalue, then called.toLowerCase()on it. A malformed JSON body such as{ "email": {} }could throw inside the async Express route before route-level handling, risking a process-level crash on the auth surface.Root cause
The route only checked
if (!email)before normalizing, unlike nearby auth handlers that require string inputs.Fix
Require
emailto be a non-empty string before normalization, then reuse the normalized value for lookup.Validation
