It was a Saturday. Doors were supposed to open at noon.
By 9 AM, the event organizer — let’s call him David — had already been awake for two hours. Not because he was nervous about the event. Because his WordPress site wasn’t loading. He refreshed. Blank page. He tried the admin panel. Wrong password, apparently. He tried the password reset. No email came.
By 10 AM, he’d called his web developer. By 11 AM, they’d gotten into the server. What they found wasn’t a crash or a server issue. Someone had been in the database. The WooCommerce orders — 400 paid ticket purchases, full names, QR codes, check-in data — were gone. All of it, deleted. The event was in an hour.
At the door, total chaos. No way to verify who had a valid ticket and who didn’t. Some people had screenshots. Some had printed PDFs. Some just showed up and said “I bought a ticket.” David ended up letting almost everyone in for free just to avoid the confrontation. By the end of the day, he’d processed a wave of refund requests from people who couldn’t prove entry, lost his revenue, and spent the next week dealing with the fallout from attendees, sponsors, and a venue that wanted to know what happened.
The cause? An unpatched plugin. Specifically, a plugin someone on his team had installed eighteen months earlier and never touched since.
How It Actually Happened
FooEvents for WooCommerce is a popular event ticketing plugin with tens of thousands of active installs. It works by turning WooCommerce orders into event tickets — which means your attendee list, ticket assignments, check-in data, and event capacity are all stored as WooCommerce order records in your database.
In late 2025, security researchers published CVE-2025-69045: a SQL injection vulnerability in FooEvents versions up to and including 1.20.4, rated CVSS 8.5 (High). The vulnerability is triggered by an authenticated user with subscriber-level access — the lowest possible privilege level, the kind of account anyone can create by registering on a site that allows user registration.
SQL injection means the attacker can send crafted input that the database interprets as commands rather than data. In this case: read everything, modify anything, delete at will. The Patchstack advisory states the vulnerability “could allow a malicious actor to directly interact with your database, including but not limited to stealing information.” In a WooCommerce environment, that database holds every ticket, every customer name, every order, every transaction record for every event on the platform.
The attack in our story requires exactly two steps. Step one: register a free account on the event site — something any visitor can do on most WordPress installations with user registration enabled. Step two: send the malicious SQL request. The result is that all WooCommerce orders are wiped. And since FooEvents uses WooCommerce orders as tickets, wiping the orders wipes every ticket for every event simultaneously.
No hacking expertise. No social engineering. No brute force. A free account and one request.
The Update That Never Happened
FooEvents patched the vulnerability in version 1.20.5. The patch existed. The fix was available. The problem — as it almost always is — was that the site never updated.
This is not a story about incompetence. David’s team installed the plugin, it worked, they moved on to other things. Plugin updates appeared in the WordPress dashboard alongside a dozen others. Nothing was obviously broken, so nothing felt urgent. The FooEvents team may have sent a security notification. It may have landed in a promotions folder, or gone to an email address that hadn’t been checked in months. Either way, the update never happened.
This is the standard failure mode. Not negligence — inattention. The plugin ecosystem generates a constant background noise of updates, changelogs, and notifications. Most of the time, ignoring them costs you nothing. Then one day it costs you everything.
Why WordPress Is the World’s Most Targeted Platform
WordPress powers 43% of every website on the internet. That scale turns it into the most efficient target for automated attacks. When you find an exploit that works on WordPress, you don’t attack one site — you attack a meaningful fraction of the entire web simultaneously.
In 2024, security researchers documented 7,966 new vulnerabilities in the WordPress ecosystem — roughly 22 per day. In 2025, that number climbed to 11,334. A 42% increase in a single year. 96% of those vulnerabilities are not in WordPress itself. They’re in plugins. Things you installed to add functionality. Things that are sitting quietly on your server right now, potentially unpatched.
43% of documented WordPress vulnerabilities require no authentication at all. No account, no credentials — just a URL and knowledge of the exploit. For the remaining vulnerabilities requiring a user account, subscriber-level access is usually sufficient, which means a free registration on your site is enough to get started.
When a new vulnerability is publicly disclosed, mass exploitation campaigns typically launch within five hours. Automated bots scan millions of sites looking for the vulnerable version string. If your site matches, it gets added to the target list — regardless of whether you’re running a major e-commerce platform or a small community event with 400 attendees. The bots don’t care about your traffic numbers.
The Numbers Behind the Damage
It’s tempting to think of a compromised website as a technical problem with a technical solution. The actual cost breakdown reframes it quickly.
Small businesses responding to a serious security incident in 2025 faced costs ranging from $120,000 to over $1.2 million when accounting for incident response, legal exposure, and recovery. Even a contained breach — one that doesn’t trigger regulatory consequences — typically runs $2,000 to $15,000 once you factor in emergency developer time, data recovery attempts, and customer communication. Google’s search ranking penalties for compromised sites take three to six months to fully recover from. 77% of customers who encounter a broken or suspicious site don’t return.
For a business built around ticketed events, the math is unforgiving. You sell tickets months in advance. Your cash flow depends on that revenue. Your reputation depends on executing the event. One incident on the morning of your biggest show of the year can erase months of work and years of trust — and there’s no version of that story where the plugin update you skipped seems like a reasonable trade-off in hindsight.
Your WordPress Site Is Your Business
There’s a mindset problem underneath most of these incidents. Site owners think of their WordPress installation as software they set up once. Attackers think of it as a business asset with a known vulnerability profile they can check programmatically at scale.
If you’re collecting payments, managing registrations, storing customer data, or running any kind of operation through your WordPress site, your installation isn’t a tool you use. It’s the infrastructure your business runs on. The standard for maintaining that infrastructure isn’t “update it when something breaks.” It’s “know what’s installed, know what’s vulnerable, and fix it before the attackers find it.”
David didn’t need to become a security expert. He needed one thing: to know, before the exploit was launched, that a plugin on his site had a critical vulnerability and an available patch. That’s not complicated. It’s not expensive. It just requires treating your WordPress site like the business asset it actually is — and having the tooling in place to monitor it automatically, rather than relying on mailing lists you might have unsubscribed from eighteen months ago.
The next event on your calendar has a date. The scanners probing your site right now do not.
Trusti Security Would Have Caught This
The vulnerability in David’s story was publicly documented with a CVE ID and a CVSS severity score of 8.5. It had a patch available. The only missing piece was someone — or something — checking whether his installation was affected.
Trusti Security’s vulnerability scanner does exactly that. It checks every plugin and theme on your site against a live vulnerability database and alerts you the moment a match is found — before the exploit reaches your site, not after. If David had Trusti installed, he would have received a notification about CVE-2025-69045 as soon as it was documented, with the affected version and the available fix clearly identified. The update would have taken two minutes. The event would have gone ahead.
Trusti also monitors your WordPress core files for unauthorized changes, logs all admin activity so you have a full audit trail if something does go wrong, and sends alerts via email, Slack, Telegram, or Pushover — whichever channel you’re actually watching.
It’s free to install and takes a few minutes to set up. The cost of not having it is something David could tell you about in detail.
