CMS Under Attack: How WordPress and Joomla Vulnerabilities Threaten Your Business
Juan Carlos Hooper
Every week, I see another business owner discover that their website has been compromised — their customer data exposed, their Google rankings destroyed overnight. And almost every time, the story starts the same way: an outdated plugin, a missed update, a vulnerability they never knew existed.
It's something I've been tracking closely for years, and what I'm seeing right now in the CMS security landscape is alarming: approximately 13,000 WordPress sites are hacked every single day. That's not a typo — and if your business runs on WordPress, Joomla, or any content management system, it should concern you deeply.
Let me walk you through what's really happening, who's being targeted, and what you can do to make sure your business isn't next.
The Scale of the Problem
WordPress powers 42.8% of all websites on the internet — roughly 9 times the market share of its nearest competitor. That dominance makes it the single biggest target for cybercriminals on the web.
When I first saw the numbers from recent security reports, I was stunned:
- 7,966 new security vulnerabilities were discovered in the WordPress ecosystem in 2024 alone — that's roughly 22 new flaws every single day
- 96% of those vulnerabilities come from plugins, not from WordPress itself
- 43% of WordPress vulnerabilities require no login or authentication to exploit — meaning anyone on the internet can attack your site
- Vulnerability disclosures increased 68% from 2023 to 2024, and the trend is accelerating
And it's not just WordPress. Joomla published 8 security advisories in 2025, including a critical SQL injection flaw. Drupal had 43 security vulnerabilities that same year. No CMS platform is immune.
Real Attacks We're Seeing in 2025
These aren't theoretical risks. Let me share some of the real incidents we've been tracking this year.
The Plugin That Gave Away Admin Access
In August 2025, a critical flaw was discovered in the Service Finder Bookings plugin for WordPress (CVE-2025-5947, rated 9.8 out of 10 in severity). This vulnerability allowed attackers to log in as any user — including the site administrator — without needing a password. Exploitation began the very next day after the patch was released, targeting every site that hadn't updated yet.
50,000 Attack Attempts in Days
Another plugin, King Addons for Elementor, had a privilege escalation vulnerability (CVE-2025-8489, also rated 9.8) that let unauthenticated attackers gain full admin access. Wordfence, one of the leading WordPress security firms, recorded approximately 50,000 exploit attempts within days of the vulnerability becoming public.
When Trusted Updates Become Weapons
Perhaps the most alarming trend I've seen is supply chain attacks — where hackers compromise the plugin update process itself. In 2024, attackers breached 5 developer accounts on WordPress.org and injected malicious code into legitimate plugins like Social Warfare and Contact Form 7 Multi-Step Addon. Then in July 2025, Gravity Forms, one of the most popular premium WordPress plugins, was similarly compromised. Businesses installed what they thought were routine updates and unknowingly gave hackers full access to their sites.
Your Website Turned Into a Malware Distributor
In January 2025, hackers exploited outdated WordPress installations to alter over 10,000 websites, replacing normal content with fake Google Chrome update pages. Visitors who clicked the "update" button downloaded malware onto their computers. The business owners had no idea their sites were being used as weapons against their own visitors.
And this isn't limited to WordPress. Joomla had a critical SQL injection vulnerability (CVE-2025-22207) in its scheduled tasks component, while Craft CMS suffered a remote code execution flaw (CVE-2025-32432) that left approximately 13,000 sites exposed, prompting a warning from CISA (the U.S. Cybersecurity and Infrastructure Security Agency).
The Business Impact Nobody Talks About
When I talk to business owners about website security, many assume the worst case is a few hours of downtime. The reality is far more devastating.
Financial Devastation
- The average cost of a cyberattack for a small-to-medium business is $254,445 — and some incidents cost up to $7 million
- According to the IBM Cost of a Data Breach Report, the global average cost of a data breach reached $4.44 million in 2025
- The most sobering statistic: 60% of small businesses close within 6 months of being hacked
Your Google Rankings Destroyed
What many business owners don't realize is that 55.40% of all CMS malware involves SEO spam — hackers inject hidden links and pages into your site to steal your search engine traffic. Google detects this and can blacklist your entire domain, showing visitors a "Deceptive Site Ahead" warning instead of your homepage.
I've seen businesses that spent years building their search rankings lose everything overnight because of a single compromised plugin. The SEO recovery alone can take months.
Customer Trust Shattered
In August 2025, the ShadowCaptcha campaign compromised over 100 WordPress sites across industries — technology, hospitality, legal, healthcare, and real estate. These sites were turned into platforms that delivered ransomware and information-stealing malware to visitors through fake CAPTCHA pages. Imagine your customers visiting your website and getting infected with malware. The reputational damage from that kind of incident is the hardest thing to recover from.
Why Attackers Love WordPress (and Joomla)
In my experience managing client websites, I've identified the key reasons CMS platforms are such attractive targets:
- Massive attack surface: WordPress alone has over 60,000 free plugins, many maintained by solo developers who may abandon them at any time
- Unpatched vulnerabilities everywhere: 35% of vulnerabilities disclosed in 2024 remain unpatched as of 2025 — and over half of plugin developers didn't even patch their code before the flaw was publicly disclosed
- "Zombie Plugins": In December 2025 alone, over 150 plugins were removed from the WordPress repository because their developers had vanished, leaving known vulnerabilities permanently unfixed
- Non-technical site owners: Many WordPress and Joomla sites are run by business owners without dedicated IT staff, meaning updates are delayed or skipped entirely
- Automated mass exploitation: Attackers use automated tools to scan millions of websites simultaneously. When a new vulnerability is published, over 30% are exploited on the same day
What We Do Differently
After years of cleaning up after breaches and helping businesses recover, I've learned that the biggest difference comes from catching problems before they happen. That's what we focus on at HooperITS — and here's what that looks like in practice:
- Proactive vulnerability monitoring and immediate patching: We track every CMS vulnerability disclosure and apply patches before attackers can exploit them — not days or weeks later, but as soon as they're available
- Plugin vetting and lifecycle management: We evaluate every plugin for security history, developer reputation, and update frequency before it goes on a client's site. And when a plugin becomes a "zombie," we replace it before it becomes a liability
- Continuous security audits and malware scanning: We don't wait for Google to blacklist your site to discover a problem. Our 24/7 monitoring and scanning catches threats early
- Backup and rapid recovery: If the worst happens, we can restore your site quickly with clean backups, minimizing downtime and data loss
And for businesses whose CMS platform has become a chronic security risk, we offer something more definitive: full CMS migration to a modern, secure architecture. We move your content, preserve your SEO rankings, and deliver a site that's typically 50-80% faster — while eliminating entire categories of plugin vulnerabilities for good.
If any of this sounds like what your business needs, we've put together CMS Migration and Maintenance plans that cover everything from ongoing security management to a full migration off a vulnerable platform — no long-term contracts required.
Don't Wait Until You're the Next Statistic
The numbers are clear: CMS vulnerabilities are growing faster than ever, attackers are more sophisticated, and the business consequences are devastating. Every day that your website runs with unpatched plugins, outdated themes, or no security monitoring is a day you're gambling with your business.
I've helped dozens of businesses recover from attacks, and I can tell you — the cost of prevention is a fraction of the cost of recovery. Don't wait until your customers see a "Deceptive Site" warning or your data ends up on the dark web.
