When that re-fetch was denied by the `_User` `get` permission, the server fell back to the raw database row, exposing raw `authData` (including MFA TOTP secrets and recovery codes) and fields hidden by `protectedFields` (when `protectedFieldsOwnerExempt` is `false`).\n\n`/verifyPassword` is the most severe: with only a username and password (no session or MFA token), an attacker who knows a victim's password could retrieve their MFA secret and recovery codes, defeating the second factor.\n\nOnly Parse Server 9.8.0 and later are affected; 8.x and earlier are not. Master and maintenance key requests are unaffected, as they bypass these controls by design.\n\n### Patches\n\nOn a denied re-fetch, `/login` and `/verifyPassword` no longer fall back to the raw row; they return only the user's identity (plus the session token for `/login`). Master and maintenance key callers still receive the full record.\n\n### Workarounds\n\nNone that preserve the intended `_User` `get` restriction.
