#37400 closed defect (bug) (invalid)

Filter in wp_object_type_exists allows for fatal error

In the wp_object_type_exists filter, if a person removes all of the object types, and returns and empty string or false, a fatal error will occur at the if statement, as it does not check to see if the data contained in the variable is empty or an array first.

function wp_object_type_exists( $object_type ) {
	 * Filters WordPress object types.
	 * @since 4.6.0
	 * @param array  $types Array of object types.
	$types = apply_filters( 'wp_object_types', array( 'post', 'comment', 'user', 'term' ) );
	if ( in_array( $object_type, $types ) ) {
		return true;
	return false;
