Wordfence security issue in 1.4

Hi,
I just updated to Innofit 1.4 and decided to run a Wordfence scan afterwards. The scan found two altered files
wp-content/themes/innofit/template/template-blog-right-sidebar.php
and
wp-content/themes/innofit/template/template-blog-full-width.php

The change I’m concerned about occurred in line 10 in each file.
<div class="container<?php echo esc_html(innofit_blog_post_container());?>">,
where the esc_html call was removed, which I guess could facilitate something like XSS.
Should I worry about this ?
