<p>There were several vulnerabilites reported against wordpress,

<p>WordPress before 4.7.19 mishandles deserialization requests in
wp-includes/Requests/Utility/FilteredIterator.php.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28033">CVE-2020-28033</a>
<p>WordPress before 4.7.19 mishandles embeds from disabled sites
on a multisite network, as demonstrated by allowing a spam
embed.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28034">CVE-2020-28034</a>
<p>WordPress before 4.7.19 allows XSS associated with global
variables.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28035">CVE-2020-28035</a>
<p>WordPress before 4.7.19 allows attackers to gain privileges via
XML-RPC.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28036">CVE-2020-28036</a>
<p>wp-includes/class-wp-xmlrpc-server.php in WordPress before
4.7.19 allows attackers to gain privileges by using XML-RPC to
comment on a post.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28037">CVE-2020-28037</a>
<p>is_blog_installed in wp-includes/functions.php in WordPress
before 4.7.19 improperly determines whether WordPress is
already installed, which might allow an attacker to perform
a new installation, leading to remote code execution (as well
as a denial of service for the old installation).</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28038">CVE-2020-28038</a>

<p>is_protected_meta in wp-includes/meta.php in WordPress before
4.7.19 allows arbitrary file deletion because it does not
properly determine whether a meta key is considered protected.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-28040">CVE-2020-28040</a>

theme's background image.</p></li>
</ul>
<p>For Debian 9 stretch, these problems have been fixed in version
