Question 1

How do I know if my site is vulnerable?

Accepted Answer

How do I know if my site is vulnerable?

To determine if your WordPress site is vulnerable, first check which version of MW WP Form you have installed. Go to Plugins > Installed Plugins and view the version listed there. If you have version 5.0.1 or below, your site is vulnerable. You can also download a security scanner like Wordfence to scan your site for known vulnerabilities. This will detect if the flaw is present.

Question 2

Can my site be hacked without me doing anything?

Accepted Answer

Can my site be hacked without me doing anything?

Yes, this vulnerability allows “unauthenticated” access meaning attackers do not need an account or any credentials whatsoever. The flaw gives free access allowing arbitrary file uploads onto WordPress sites running MW WP Form at version 5.0.1 or lower. This means your site can potentially be compromised without any action on the admin or user end.

Question 3

How urgent is it that I update?

Accepted Answer

How urgent is it that I update?

It is extremely urgent to update as soon as possible. This vulnerability received a 9.8 CVSS severity score making it critical. Attacks could lead to total site takeovers, data theft, black hat techniques and more. WordPress vulnerabilities like this often see automated mass attacks as well once details emerge.

Question 4

What could happen if my site gets hacked using this vulnerability?

Accepted Answer

What could happen if my site gets hacked using this vulnerability?

A number of bad outcomes are possible if your site gets hacked via this arbitrary file upload flaw. Attackers may upload backdoors to steal data like credentials or customer information. They could also add malicious redirects, install cryptominers impacting site performance, initiate DDoS attacks from your server or otherwise sabotage your site and business.

Question 5

Is updating to the latest version enough to fully protect my site?

Accepted Answer

Is updating to the latest version enough to fully protect my site?

While updating closes the door on this specific vulnerability, your site may still have malicious files present if it was compromised earlier when outdated. You’ll want to check wp-content and other file directories for anything suspicious uploaded such as unexpected .php files, redirects or base64 code. Removing those remnants can help fully disinfect your site.

Question 6

Should I find a different plugin since this one has had previous security issues too?

Accepted Answer

Should I find a different plugin since this one has had previous security issues too?

Given that MW WP Form has faced multiple vulnerabilities over the past several months, you may want to consider replacing it with a more security-focused alternative. Plugins like Contact Form 7, Formidable Forms, WPForms and Ninja Forms offer robust features without presenting the same security risks. Migrating away from problem plugins is smart website hygiene.

Question 7

What security steps should I take in addition to upgrading?

Accepted Answer

What security steps should I take in addition to upgrading?

On top of upgrading MW WP Form, enable two-factor authentication on your WordPress admin account to prevent unauthorized logins. Limit admin access to trusted IP addresses only. Install a web application firewall to continually monitor activity looking for attacks. Maintain regular backups you can restore from if issues emerge. Sign up for site monitoring alerts to stay informed of other plugin/theme vulnerabilities.

Question 8

Should I hire a developer to handle this update for me?

Accepted Answer

Should I hire a developer to handle this update for me?

If you have limited technical skills, hiring a developer to handle the update is perfectly reasonable to ensure it is done properly. An expert can scan for backdoors, walk you through identifying any malicious code present and removal steps, test form functionality post-update and validate no breakage occurred. This gives peace of mind.

Question 9

What can I do if I don’t understand any of the technical website update work you referenced?

Accepted Answer

What can I do if I don’t understand any of the technical website update work you referenced?

If the technical details around vulnerabilities, file transfers, disinfection protocols etc. feel confusing and intimidating, don’t worry! Reach out for help from a trusted WordPress developer or managed hosting provider. You don’t need to handle highly technical security details yourself. Lean on experts who can accurately assess your site’s integrity and provide easy-to-digest guidance tailored to your comfort level.
