Critical vulnerabilities in WordPress plugins – February 2022


To ensure that your WordPress website is secure and stays that way, you need to have a security plugin.

One reason is that they report regularly on critical vulnerabilities of plugins you might use.

There are few available, although my preference goes to Wordfence.

Critical vulnerabilities in WordPress plugins – February 2022

The Wordfence Threat Intelligence team found sofar these vulnerabilities:

Remote Code Execution vulnerabilities in PHP Everywhere

A WordPress plugin installed on over 30,000 websites.

One of these vulnerabilities allowed any authenticated user of any level, even subscribers and customers, to execute code on a site with the plugin installed.

As such, it was possible for any logged-in user, even a user with almost no permissions, such as a Subscriber or a Customer, to execute arbitrary PHP on a site.

If you’re using the PHP everywhere plugin, it is imperative that you upgrade to the newest version, which is 3.0.0 at the time of this writing, in order to prevent your site from being exploited.

Unfortunately, version 3.0.0 only supports PHP snippets via the Block editor, so if you are using the Classic Editor, you will need to uninstall the plugin and find another solution.

You should not continue to run older versions of PHP Everywhere under any circumstances.

Backups are a treasure trove of sensitive information and frequently include configuration files which can access the site database and the contents of the database itself.

This vulnerability was patched in version 1.22.3 of UpdraftPlus, and to you to verify that your site is running the most up-to-date version of the plugin and updating immediately if it is not.
