This morning we were alerted to a report of a vulnerability that was responsibly disclosed to the WordPress.org team.
They informed us of the nature of the vulnerability and asked us to take a look and patch it.
This quick article is an outline as to the nature of the vulnerability and statement that it’s been fixed.
What’s the nature of the vulnerability?
This vulnerability is quite limited, and comes into play mainly on older versions of Internet Explorer.
This security bug was applicable only when:
- you were using the option to hide your WordPress login URL
- the site visitor was using a generic mobile browser or an old version of Internet Explorer
- the site visitor could be tricked into trying to access the normal login URL or WP admin area while not being logged-in. i.e. there is/was no danger of scripts executing under elevated WP priviledges.
So while the risk was quite low, it is still a risk and we recommend everyone upgrade to the latest version of Shield Security 8.2.3.
Are you safe?
As we mentioned, the scope of exploiting this vulnerability is very limited, and it can’t ever be triggered by a user while they’re logged into a site.
But, while the risk isn’t high, you should upgrade all installations of Shield Security to ensure all visitors to your site are safe.
Please upgrade as soon as you possibly can.
To handle just this sort of scenario, Shield has had built-in auto-upgrade functionality since auto-upgrade were available to WordPress. This means that for people who don’t see this notice, and haven’t adjusted their settings, their Shield plugins will be upgraded automatically in a few days.
We strongly urge you to upgrade your Shield Security installation as soon as you can.
How did this happen?
This is Shield Security’s first security issue and while we hope it’ll be the last, we can never make such a promise.
We, obviously, take security seriously and to have a vulnerability in our plugin is a great concern for us. We take measures to ensure this doesn’t happen.
This security issue was reported to us 7 hours ago, and since then we’ve completed the code changes to fix it, written this quick article to outline what’s happened, and released the Shield upgrade to the public that addresses it.
We don’t take this sort of situation lightly.
The code being referenced here is somewhat older code and hasn’t undergone the rigour that our newer code has, and it’s slipped through the net.
We’re taking the time to review all our older code and where we can shore it up, we’ll do so.

Well done, my go-to security plugin
I use this plugin on all the sites in our agency. I appreciate how he feels about security and minimal hype. Feedback had been much better received than some I have communicated with. By nature, a security plugin is fairly technical but I think this has been well executed. Thanks…
Thanks for this great plugin!
Easy to use and configure – recommend for every site!
The title says it all. This plugin just works – it is easy to use and configure, with a range of options that do what they promise. Of course no firewall plugin can completely prevent attacks but this plugin certainly makes your site that bit harder to attack which makes…
Great Firewall werkt perfect!
