Token refresh and password reset responses could return fields that the requesting user did not have access to.
You are affected if:
Authentication responses now apply field access and hidden-field filtering before returning user documents. Full user documents remain available server-side for access control.
Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
Custom authentication strategies remain responsible for filtering user documents returned through custom responses.
There is no complete workaround. Users should upgrade Payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
