CVE-2026-105853: Payload: Token refresh and password reset responses may expose restricted user fields

## Impact Token refresh and password reset responses could return fields that the requesting user did not have access to. You are affected if: - An authentication collection contains hidden or read-restricted fields. ## Patches 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. ## Workarounds There is no complete workaround. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
