Coding Style Compatibility introduced by
PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

You can fix this by adding a namespace to your class:

namespace YourVendor;

class YourClass { }

When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

Documentation introduced by
The property $rest_read is declared protected in CMB2_REST. Since you implemented __get(), maybe consider adding a @property or @property-read annotation. This makes it easier for IDEs to provide auto-completion.

Since your code implements the magic setter _set, this function will be called for any write access on an undefined variable. You can add the @property annotation to your class or interface to document the existence of this variable.

<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}

Since the property has write access only, you can use the @property-write annotation instead.

Of course, you may also just have mistyped another name, in which case you should fix the error.

See also the PhpDoc documentation for @property.

Bug Best Practice introduced by
The return type of return $this->rest_box; (CMB2_REST) is incompatible with the return type of the parent method WP_REST_Controller::get_item of type WP_Error|WP_REST_Response.

If you return a value from a function or method, it should be a sub-type of the type that is given by the parent type f.e. an interface, or abstract method. This is more formally defined by the Lizkov substitution principle, and guarantees that classes that depend on the parent type can use any instance of a child type interchangably. This principle also belongs to the SOLID principles for object oriented design.

Let’s take a look at an example:

class Author {
    private $name;

    public function __construct($name) {
        $this->name = $name;
    }

    public function getName() {
        return $this->name;
    }
}

abstract class Post {
    public function getAuthor() {
        return 'Johannes';
    }
}

class BlogPost extends Post {
    public function getAuthor() {
        return new Author('Johannes');
    }
}

class ForumPost extends Post { /* ... */ }

function my_function(Post $post) {
    echo strtoupper($post->getAuthor());
}

Our function my_function expects a Post object, and outputs the author of the post. The base class Post returns a simple string and outputting a simple string will work just fine. However, the child class BlogPost which is a sub-type of Post instead decided to return an object, and is therefore violating the SOLID principles. If a BlogPost were passed to my_function, PHP would not complain, but ultimately fail when executing the strtoupper call in its body.

Compatibility Best Practice introduced by
Use of global functionality is not recommended; it makes your code harder to test, and less reusable.

Instead of relying on global state, we recommend one of these alternatives:

1. Pass all data via parameters

function myFunction($a, $b) {
    // Do something
}

2. Create a class that maintains your state

class MyClass {
    private $a;
    private $b;

    public function __construct($a, $b) {
        $this->a = $a;
        $this->b = $b;
    }

    public function myFunction() {
        // Do something
    }
}

Documentation introduced by
$cmb is of type object<CMB2>, but the function expects a object<CMB2_REST>.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Documentation introduced by
The property cmb_id does not exist on object<CMB2_REST>. Since you implemented __get, maybe consider adding a @property annotation.

Since your code implements the magic getter _get, this function will be called for any read access on an undefined variable. You can add the @property annotation to your class or interface to document the existence of this variable.

<?php

/**
 * @property int $x
 * @property int $y
 * @property string $text
 */
class MyLabel
{
    private $properties;

    private $allowedProperties = array('x', 'y', 'text');

    public function __get($name)
    {
        if (isset($properties[$name]) && in_array($name, $this->allowedProperties)) {
            return $properties[$name];
        } else {
            return null;
        }
    }

    public function __set($name, $value)
    {
        if (in_array($name, $this->allowedProperties)) {
            $properties[$name] = $value;
        } else {
            throw new \LogicException("Property $name is not defined.");
        }
    }

}

If the property has read access only, you can use the @property-read annotation instead.

Of course, you may also just have mistyped another name, in which case you should fix the error.

See also the PhpDoc documentation for @property.
