Gokapi vulnerable to Privilege Escalation in File Replace
## Summary An insufficient authorization check in the file replace API allows a user with only list visibility permission (`UserPermListOtherUploads`) to delete another user's file by abusing the `deleteNewFile` flag, bypassing the requirement for `UserPermDeleteOtherUploads`. ### Impact Any authenticated user with `PERM_REPLACE` (replace own files) and `PERM_LIST` (view other users' uploads) can delete any other user's file without needing `PERM_DELETE`.
