Payload authentication token field handling issue

Impact

Under certain field configurations, Payload could include unintended values in the authentication token issued at login.

You are affected if:

• You use an affected Payload version and have configured a custom field option that maps a field to a reserved authentication claim name.

Patches

Payload now restricts which field configuration options can influence the contents of the authentication token.

Users should upgrade payload packages to >= 3.90.0 or >= 4.0.0-canary.34.

Workarounds

There is no complete workaround. Users should upgrade payload packages to >= 3.90.0 or >= 4.0.0-canary.34.
