Utilizing JavaScript to Manage Post Status on WP REST API

I've been diving into WP REST API and have gone through several tutorials. I'm currently delving into using JavaScript to create new posts.

In this particular tutorial, the post var status = 'draft'; is mentioned (check out the code above). However, I can't help but wonder if this status could be vulnerable to hacking?

jQuery( document ).ready( function ( $ ) {
    $( '#post-submission-form' ).on( 'submit', function(e) {
        e.preventDefault();
        var title = $( '#post-submission-title' ).val();
        var excerpt = $( '#post-submission-excerpt' ).val();
        var content = $( '#post-submission-content' ).val();
        var status = 'draft'; // this part of the code

        var data = {
            title: title,
            excerpt: excerpt,
            content: content
        };

        $.ajax({
            method: "POST",
            url: POST_SUBMITTER.root + 'wp/v2/posts',
            data: data,
            beforeSend: function ( xhr ) {
                xhr.setRequestHeader( 'X-WP-Nonce', POST_SUBMITTER.nonce );
            },
            success : function( response ) {
                console.log( response );
                alert( POST_SUBMITTER.success );
            },
            fail : function( response ) {
                console.log( response );
                alert( POST_SUBMITTER.failure );
            }

        });

    });

} );

One challenge with javascript/jquery requests is that users have the ability to manipulate the data being sent since it resides client-side

Verifying the authenticity of data coming from a client can be difficult. This responsibility often falls on the server to validate each incoming request. The most secure way to prevent users from submitting altered values is by handling validation server-side. Any actions taken client-side are susceptible to manipulation by any visitor to your website.
