Is Your Business Website Safe Right Now? Critical PHP flaw.

A major internet security flaw was just discovered. Here's what every Austin business owner needs to know — and do — today.

On October 21, 2026, security researchers discovered two critical flaws in PHP — the invisible software engine that runs most of the world's websites. Within hours, CISA, the federal agency that oversees cybersecurity, issued an emergency alert. Hackers started trying to exploit these flaws before the patch was even publicly announced. This is a fast-moving situation.

You don't need to be technical to take action. You just need to know what to ask and who to call. That's what this blog is for.

What Is PHP and Why Does It Matter to My Business?

Think of PHP as the engine under the hood of your website. You've probably never heard of it, you're not supposed to. But there's a good chance it's quietly running your business website, your online booking system, your client portal, or other web-based tools your team uses every day.

The platform that powers your website, WordPress, for example almost certainly uses PHP. So do many scheduling systems, patient portals, billing tools, and industry-specific applications. Researchers identified over 22 million vulnerable systems exposed to the internet. If you have a website, the odds are high that this affects you.

What Actually Happened?

Two security flaws were found in PHP. Both allow a hacker to break into your website or business systems without needing a password or any help from your team. No clicking on a bad link. No tricked employee. Just a hacker on the internet sending the right request to your server and getting full control of it.

The federal government rated these at 9.2 out of 10 on the severity scale. A 10 is the worst

possible. Patches were released on October 21, 2026. If your systems haven't been updated, they're still wide open.

Does This Affect My Business?

You're likely at risk if any of the following apply:

Your business has a website (especially one built on WordPress)
Your team uses an online scheduling, billing, or patient management system
Clients log into a portal to access documents or their account
You have a custom web application built for your industry
Your website was built by a designer and you're not sure what's under the hood
You use an e-commerce store or take orders online

If you're not 100% certain your website doesn't run PHP, assume it does and act accordingly.

What to Do Right Now

You don't need technical knowledge to take these steps. Follow them in order.

1. Find out who manages your website and web systems.

The first call goes to whoever built or currently hosts your website. That might be a web designer, a marketing agency, your hosting company (GoDaddy, Bluehost, WP Engine, etc.), your IT provider, or an internal staff member. If you're not sure who to call, search your email for your original website invoice or your hosting renewal notices. That company's contact info will be there.

2. Ask this exact question.

When you reach your web host or IT provider, ask them:

"Has our website been patched for the critical PHP security vulnerability discovered on October 21, 2026? Are we running an updated version of PHP?"

A good provider should answer quickly and tell you what version you're running, whether it's been updated, and their timeline if it hasn't been patched yet.

Red flag: If they don't know what you're talking about or say "we'll look into it," push harder or get a second opinion. This has been a publicly documented emergency since October 21. Any reputable provider should already be on it.

3. Check your industry-specific software.

Beyond your website, think about other web-based tools your business relies on — scheduling, billing, intake forms, patient portals, practice management software. Contact each vendor and ask the same question. Reputable vendors should have already issued an update or published a security notice. Check their website for a status page or security advisory if you can't reach them immediately.

4. Do a quick visual check yourself.

You don't need technical skills to spot obvious signs of a problem. Visit your own website as a customer would. Look for anything that seems off — pages that look broken, unexpected pop-ups, unfamiliar links, redirects to a site you don't recognize, or any login prompts you didn't create.

Ask a few employees to check from their own devices as well. If anything looks wrong, take a screenshot and report it to your IT provider right away.

5. Get confirmation in writing.

Once your provider confirms you've been patched, ask them to send a quick email confirming it. This creates a paper trail — especially important for businesses in regulated industries like legal, medical, dental, and financial services.

What If I Don't Have an IT Provider?

A lot of small businesses run without dedicated IT support — relying on whoever built the website years ago or a resourceful staff member. That works fine most of the time. This is not most of the time.

Here's what you can do right now:

Contact your web hosting company directly. Most have 24/7 support and many have already patched their shared hosting environments automatically.
If your site runs WordPress, log into your WordPress admin panel and look for any security-related updates flagged in the dashboard.
Reach out to a local IT provider for a quick check. Verifying your patch status typically takes under an hour.

The RIATA Take

Situations like this expose a gap that most small businesses don't know they have. Nobody is watching your website security the way a dedicated IT partner does. Most business owners find out something went wrong after a client calls to say your site looks strange — or worse, after data has already been accessed.

As an Austin-based, locally owned MSP, we work with law firms, dental and medical practices, financial advisors, and the startups giving this city its energy. We can verify your patch status, walk you through the conversation with your host, or just tell you honestly whether you're exposed. If everything's solid, we'll tell you that too.

Give us a call. The check is free. The peace of mind is priceless.
