What’s Bricks Builder and Why Do So Many Use It?

Bricks Builder has become a favorite among WordPress users looking for a fast, flexible site-building experience. It’s a performance-first, visual page builder that gives you full control over design without adding unnecessary weight to your site. Instead of bloated code, it focuses on a clean, developer-friendly structure with features that appeal to both beginners and advanced users.

• Visual builder tools: Drag-and-drop interface that updates in real time.
• Custom responsive design: Support for unique breakpoints tailored to different devices.
• Dynamic content support: Easily integrates custom fields and dynamic values.
• Theme-building functions: Allows for full header, footer, archive, and single page customization.
• Developer-friendly interface: Built with performance, flexibility, and clean markup in mind.

Despite all these great features, one critical issue has recently come to light that could put every Bricks Builder-powered site at serious risk.

What’s the Deal With This Remote Code Execution Bug?

Security researchers uncovered a serious vulnerability in Bricks Builder that lets hackers run their own code on your WordPress site. This is known as a Remote Code Execution (RCE) bug, and it’s about as bad as it gets. It allows an attacker to take over your site completely—and in some cases, even your entire server.

• Bug source: The problem lies in how the plugin handles AJAX requests—particularly the bricks_save_post function.
• Main issue: The function didn’t properly check user roles or verify nonces, which are normally used to prevent unauthorized actions.
• Resulting flaw: Low-level users like subscribers could exploit this loophole to inject malicious PHP code.

Once that code is in, it runs like any other file on your server, meaning full access for the attacker.

Just How Bad Is This Vulnerability?

This RCE flaw is present in all Bricks Builder versions released before version 1.9.6. That includes any site built on older versions, whether custom-developed or run by agencies.

• Targeted versions: Any release before version 1.9.6.
• Scope of access: Attackers can do everything from adding admin accounts to uploading malware or altering existing files.
• Potential damage: Site defacement, stolen data, persistent backdoors, and even server-level control.

If your site lets users register accounts, even something as harmless as a subscriber role becomes a gateway for full compromise.

Key takeaway: Just one unpatched site could give an attacker total control using nothing more than a basic user account and a malicious request.

How Hackers Are Exploiting This Bug

This isn’t some complex, elite-level hack. It’s simple and effective—and that’s what makes it dangerous. Hackers can use a basic account and a few lines of code to gain full access.

• Create a new user account: Most WordPress sites allow subscriber-level registration.
• Send a crafted POST request: The attacker targets admin-ajax.php with a custom payload.
• Inject PHP into template data: That code then executes like it’s part of your theme or plugin.
• Take over the system: From there, it’s game over—admin privileges, malware uploads, or full server access.

Once exploited, the attacker could even hide their presence using obfuscated code or hidden files, making it harder to detect without a deep forensic check.

What’s Been Done So Far?

The Bricks Builder team acted quickly after being notified of the vulnerability. Within 48 hours, they released a fix and notified users.

• Fixed version: Bricks Builder 1.9.6.
• Patch coverage: The update blocks unauthorized access, validates user roles, and verifies all AJAX actions using proper nonce checks.
• User recommendation: All users should update immediately to 1.9.6 or later to stay protected.

If you’re not ready to update for some reason, you should take temporary protective measures such as limiting user registration and firewalling the admin-ajax.php endpoint.

Signs That Your Site Might Be Compromised

Not sure if your site was hit? There are several indicators that could point to a successful exploit. These signs don’t guarantee compromise but definitely warrant further inspection.

• Strange user activity: Unknown admin accounts showing up.
• Unusual files: PHP files suddenly appearing in wp-content/uploads/ or other public folders,
• Performance spikes: High CPU or bandwidth usage without traffic surges.
• Modified core files: Changes to functions.php, .htaccess, or wp-config.php without your knowledge.
• Server logs: Repeated access to admin-ajax.php from suspicious IPs.

To fully check your site, use security tools like WPScan or Wordfence. These can scan for known malware signatures and changes to critical files. You should also manually inspect modified timestamps on plugin and theme files.

How the Bricks Team Is Handling It

The Bricks Builder developers deserve credit for handling the issue quickly and transparently. They didn’t try to downplay the severity and immediately released a patch with proper safeguards.

• Public advisory: Posted shortly after patch release with clear mitigation instructions.
• Security-first roadmap: Future releases will include more code review steps, automated testing for permissions, and improved handling of user input.
• Bug reporting channel: Opened a secure channel for researchers to disclose vulnerabilities moving forward.

This type of response builds trust—and it’s a good reminder that no plugin is perfect, but developer accountability makes a big difference.

What WordPress Users Should Learn From This

This bug serves as a serious reminder to everyone using WordPress: even well-built plugins can introduce huge security risks if not properly audited or maintained. It’s not just about keeping WordPress core updated—you need to stay on top of your plugin stack too.

• Control user roles: Limit editing and publishing capabilities to trusted users only.
• Disable open registration: Unless it’s essential, stop allowing anyone to create an account.
• Use security tools: Firewalls, malware scanners, and monitoring tools can catch threats early.
• Update regularly: Never delay updates for plugins, especially when they include security patches.
• Scan and back up often: Maintain clean backups and perform file integrity checks routinely.

A site may look fine on the surface, but with a vulnerability like this, attackers could be operating quietly in the background.

Conclusion

The Bricks Builder RCE bug is a serious threat that impacted a widely-used WordPress plugin. Fortunately, the developers acted fast, and a fix is available in version 1.9.6. If you haven’t updated yet, do it now—then take a few minutes to inspect your site for signs of compromise and adjust your user permissions if needed.

Security should never be an afterthought. Whether you’re managing one site or fifty, staying up to date on plugin vulnerabilities is a critical part of running a safe, stable website.

Key takeaway: A serious vulnerability in Bricks Builder allowed attackers to run code remotely. Anyone using versions below 1.9.6 must update immediately and inspect their site for suspicious activity.

FAQs

Is Bricks Builder safe now?

What Is Google Tag Manager?

• Definition: Google Tag Manager (GTM) is a free tool that lets you add and manage tracking codes on your WordPress site without touching the code directly.
• Purpose: It acts like a central hub for scripts such as Google Analytics, Facebook Pixel, and other marketing tools.
• Functionality: You control when and where those scripts fire, all from a single dashboard.

Instead of pasting new code into your site for each marketing tool, GTM lets you add or update all those tags in one place. This keeps your site clean and cuts down on errors.

Why Use Google Tag Manager With WordPress?

• Centralized Control: You get one easy-to-use interface to manage all your tags.
• No Need for Developers: Anyone with basic web knowledge can use GTM—no coding required.
• Better Performance: GTM loads scripts asynchronously, which helps your pages load faster.
• Error Reduction: Built-in tools help test and troubleshoot your tags before publishing.
• Flexible Tracking: Set up custom triggers to track clicks, scrolls, form submissions, and more.

Key takeaway: GTM gives you complete control over your site’s marketing and tracking codes—all without touching your site’s core files after setup.

What You Need Before You Start

• Google Account: Required to create and access your GTM container.
• Admin Access to WordPress: Needed to add code manually or install and configure plugins.
• Optional Analytics Setup: While not required, setting up Google Analytics alongside GTM is common practice for tracking visitor behavior.

Create a Google Tag Manager Account

To get started with GTM:

• Go to https://tagmanager.google.com and log in with your Google account.
• Click Create Account and enter your company or website name.
• Select your country.
• Enter your website’s domain name as the container name
• Choose Web as the target platform.
• Agree to the terms and click Create.

You’ll receive two code snippets—one for the <head> and one for just after the opening <body> tag. Copy both and keep them nearby.

Grab Your GTM Tracking Code

• Head Snippet: This should be placed inside your site’s <head> tag and is used to load the GTM container script.
• Body Snippet: This goes immediately after the <body> tag and acts as a fallback for users without JavaScript enabled.

Both snippets are necessary for full functionality. Don’t skip either one.

Add GTM to WordPress Manually

If you’re comfortable with a little code, manual installation is simple.

• In your WordPress dashboard, head to Appearance > Theme File Editor.
• Locate and open header.php.
• Paste the head snippet right before the closing </head> tag.
• Paste the body snippet immediately after the opening <body> tag, if available in the same file or in footer.php.
• Click Update File to save changes.

Remember, theme updates can wipe out your changes. Use a child theme to keep your custom code safe.

Add GTM Using a Plugin

For a no-code approach, plugins work great. Two solid options are:

• Insert Headers and Footers by WPCode
• DuracellTomi’s Google Tag Manager for WordPress

Using Insert Headers and Footers:

• Go to Plugins > Add New, search for “Insert Headers and Footers,” and install it.
• After activating, go to Settings > Insert Headers and Footers.
• Paste the GTM head code into the “Scripts in Header” box.
• If there’s a field for “Scripts in Body,” place the body snippet there.
• Click Save.

Using DuracellTomi’s Plugin:

• Install the plugin through Plugins > Add New by searching “DuracellTomi Google Tag Manager.”
• Activate it and go to Settings > Google Tag Manager.
• Enter your GTM container ID (e.g., GTM-XXXXXX).
• Enable any extra features like WooCommerce support or AMP compatibility.
• Save your settings and verify your setup.

Plugins are ideal for keeping GTM working even when you update or switch themes.

Test and Verify That GTM Is Working

Testing your setup ensures everything is running correctly.

• Preview Mode: Open GTM, click “Preview,” and enter your website URL. A debug panel will open at the bottom of your site showing which tags are firing.
• Chrome Extension: Use the Tag Assistant (Legacy) extension. Visit your site, click the extension, and it will show if GTM and other tags are working properly.
• Common Fixes: If you don’t see GTM working, check code placement, confirm you saved changes, and make sure no plugins are blocking the scripts.

Always verify your installation before deploying live tags.

Connect Google Analytics With GTM (Optional)

To use Google Analytics through GTM:

• In your GTM dashboard, click Tags > New.
• Choose Google Analytics: GA4 Configuration.
• Enter your GA4 Measurement ID (found in your Analytics Data Stream).
• Set the trigger to All Pages.
• Click Save, then Submit and Publish your container.

With this setup, GA4 tracks your visitors using GTM, keeping your implementation clean and centralized.

Watch Out for These Common Mistakes

• Wrong Code Placement: Always place the head and body snippets exactly where Google recommends.
• Duplicate Containers: Avoid adding more than one GTM container to your site. It causes conflicts and duplicate tracking.
• Unpublished Changes: Changes in GTM aren’t live until you hit Submit in the GTM interface.
• Plugin Conflicts: Some security or optimization plugins might block GTM. Whitelist your scripts if needed.
• Skipping Testing: Always run GTM in preview mode or use Tag Assistant to confirm everything’s working before publishing tags.

Conclusion

Adding Google Tag Manager to WordPress doesn’t take much time, but it opens up powerful tracking and tag management features. Once set up, GTM gives you the flexibility to add, adjust, and troubleshoot tags without editing code or relying on developers. Whether you prefer adding it manually or using a plugin, the result is the same—you get full control over the tracking tools that keep your site running smarter.

Key takeaway: Google Tag Manager is the simplest and most efficient way to manage tracking scripts in WordPress. With the right setup, you’ll spend less time worrying about code and more time focusing on the insights those tags deliver.

FAQs

Can I use Google Tag Manager on multiple WordPress sites?

Yes, but you’ll need to create a unique container for each site within your GTM account. Avoid reusing containers to prevent tag confusion or cross-site data leakage.

Is Google Tag Manager really free?

Absolutely. GTM is 100% free with no hidden charges, regardless of how many containers or tags you manage.

Does GTM replace Google Analytics?

No, GTM doesn’t collect data on its own. It simply helps you deploy Google Analytics and other tracking tools more efficiently.

Can I run A/B tests through GTM?

Yes, GTM works with tools like Google Optimize and other testing platforms. You can load test variations using triggers and tags.

What happens if I uninstall the GTM plugin?

If you remove the plugin and haven’t added the GTM code manually elsewhere, your tags will stop firing. Make sure GTM is embedded another way before deactivating any plugin.

What Really Happened with the WP Site Builder Add-on?

The WP Site Builder add-on was discovered to contain a malicious backdoor. This wasn’t a minor bug or a coding error—it was intentional. Hackers embedded code that quietly gave them access to WordPress sites that had the plugin installed. Even though everything looked fine at the surface, the plugin had hidden PHP scripts running in the background.

What the backdoor did:

• Granted Remote Access: Attackers could control affected sites from outside the network.
• Modified Files: They could inject more malicious code into plugin or theme files.
• Escalated Privileges: In some cases, they created fake admin accounts to maintain access.

Because the code was hidden and activated under specific conditions, it went undetected for a while. By the time many site owners realized something was wrong, it was already too late.

Why This Affects All WordPress Users

No matter how small or large your site is, if you were using the infected WP Site Builder add-on, your security may have been compromised. The backdoor made it easy for outsiders to sneak in and take control.

Risks from the breach include:

• Data Exposure: Customer details, user credentials, and emails may have been accessed or stolen.
• Spam and Redirects: Hackers could redirect your site visitors to phishing or spam pages.
• Reputation Damage: Search engines may blacklist your domain, and users may report your site as dangerous.
• Resource Hijacking: Your server could have been used to send spam emails or run botnets.

Many users only noticed when search rankings dropped or when browser warnings appeared. Others didn’t find out until security plugins flagged the issue.

How to Spot a Compromised Site

Even if your site seems fine, hidden malware might still be running. Subtle signs can help you identify a breach before it becomes worse.

Watch out for these warning signs:

• Strange Files or Code: New PHP files appear in plugin folders, or existing ones contain garbled or encoded text.
• Unknown Users: Unfamiliar admin accounts show up in your dashboard.
• Suspicious Behavior: Your site redirects visitors or loads random content.
• Performance Drops: The site slows down, consumes more server resources, or crashes frequently.
• Error Logs: System logs show unauthorized access attempts or calls to unknown scripts.

Even a small change in site behavior could mean something’s wrong under the hood.

Steps to Check If You’re Affected

It’s critical to act quickly. Checking your site manually and with tools can help you identify whether you’ve been targeted.

Do the following to investigate:

• Manually Inspect Plugin Files: Go to /wp-content/plugins/ and open the WP Site Builder add-on directory. Look for recent modifications or suspicious file names.
• Run Security Scans: Use plugins like Wordfence, Sucuri, or MalCare to scan for malware or file changes.
• Check Plugin Version: Compare your version to security advisories and changelogs. If it’s on the list of affected versions, assume it may be compromised.
• Review Site Config Files: Open .htaccess and wp-config.php for any added code or encoded lines you didn’t place there.
• Enable Debug Logs: Activate WP_DEBUG in wp-config.php to see what errors or warnings show up in the debug log.

Being thorough now saves you time, money, and reputation later.

How to Clean and Secure Your Website

If you confirm that your site was compromised, don’t panic. You can restore control, but it requires deliberate action and cleanup.

Here’s what you need to do:

• Delete the Plugin: Completely remove the add-on from your plugin directory—not just deactivate it.
• Remove Malicious Files: Go through your site files and delete anything unusual. Compare with clean WordPress core files if needed.
• Reinstall WordPress Core: Download a fresh copy of WordPress and overwrite core files to ensure no core files were modified.
• Change All Passwords: Update passwords for all WordPress admin users, database users, hosting accounts, and FTP logins.
• End All Sessions: Force logout all users and remove any lingering login tokens.
• Check for Extra Users: Delete any suspicious users with admin rights.
• Scan Again: After cleaning, run another security scan to confirm the site is clean.
• Submit Site for Review: If your site was blacklisted or flagged, submit a request to Google Search Console or security services to clear the warning.

A clean site is only the beginning—keeping it clean requires ongoing effort.

Tips to Stay Protected in the Future

Cleaning your site is important, but preventing another breach should be your next priority. These best practices will help you keep things locked down.

What you should always do:

• Use Trusted Sources: Only install plugins and themes from the WordPress directory or trusted developers.
• Check Plugin Updates: Read changelogs before updating to know what’s being changed or added.
• Monitor File Changes: Use tools that alert you when plugin, theme, or core files are modified.
• Limit Plugin Use: Don’t overload your site with unnecessary plugins. Fewer plugins mean fewer risks.
• Enable Two-Factor Authentication: Require it for all admin users to stop brute-force logins.
• Create Off-Site Backups: Schedule daily or weekly backups and store them off your server.
• Install a Security Plugin: Choose a reliable one that includes malware scanning, firewall rules, and brute-force protection.

Key takeaway: Don’t wait until a breach forces you to act. Make plugin hygiene, routine scans, and data backups a regular part of your website management.

How Developers and the Community Responded

When the issue was discovered, users flooded support forums with concerns. In some cases, the plugin’s developer denied responsibility. In others, the plugin was quietly removed from directories with little explanation.

The WordPress community responded quickly:

• Security Teams Issued Alerts: Wordfence, Patchstack, and others shared public notices and offered cleanup advice.
• Blog Posts Spread the Word: Researchers published deep dives into how the backdoor worked and what to look for.
• Patches Were Released: In some cases, unofficial fixes circulated while the original developer stayed silent.

The open-source community acted faster than expected, but the situation highlighted how easily one plugin can put thousands of sites at risk.

Conclusion

The WP Site Builder add-on backdoor was a wake-up call for many site owners. Even trusted plugins can turn into major vulnerabilities with just one bad update. What makes this issue particularly concerning is how silently it operated. It didn’t crash sites or throw errors—it simply gave hackers the keys and let them walk in unnoticed.

For WordPress site owners, the lesson is clear. Always know what’s running on your site. Monitor plugin activity. Pay attention to changelogs. And when something feels wrong, don’t brush it off.

Key takeaway: Website security isn’t a one-time fix. It’s a routine. Staying proactive with scans, updates, and backups is the best way to avoid surprises like this.

FAQs

What should I do if I used the infected plugin months ago?

Even if you deleted it, hidden backdoors might still be active. Run a full security scan, compare current files with backups, and check for unauthorized users or leftover scripts.

Can this kind of backdoor spread to other parts of my website?

Yes. Once the backdoor is active, it can affect themes, other plugins, or server-level config files. That’s why you need a complete scan of all site directories.

Is it safe to continue using WP Site Builder now?

That depends on where you got it and which version you’re using. Only use versions confirmed clean by security researchers. Otherwise, consider switching to an alternative builder.

Will Google penalize my site for being hacked?

Yes. If Google finds malware or spam, your site could be flagged or dropped from search results. Once cleaned, submit a review request in Google Search Console.

How do I know this wasn’t part of a bigger plugin attack?

Check updates from security platforms like Wordfence or Patchstack. If multiple tools from the same developer or publisher are involved, it may be part of a broader supply chain issue.

What Went Down With the Plugin

A critical vulnerability was recently discovered in a WordPress plugin installed on over a million websites. This wasn’t a minor bug—it allowed attackers to run remote code and possibly inject malicious SQL commands directly into site databases. That’s as serious as it gets.

Security researchers discovered the flaw during a routine audit. Fortunately, the plugin developers moved fast. Here’s the timeline:

• Vulnerability discovered: July 18, 2025
• Patch released: July 24, 2025
• Public disclosure: July 30, 2025

Now, the responsibility falls on WordPress users to update the plugin to the patched version.

Who’s in the Danger Zone

This plugin isn’t just for niche use—it’s everywhere. Whether you run a blog, a personal portfolio, a business site, or a full-blown online store, there’s a good chance this plugin is either installed directly or bundled with a theme you’re using.

• Used on: eCommerce stores, lead-gen websites, online memberships
• Bundled with: popular WordPress themes and page builders
• Often installed unknowingly: via auto-installs from hosting platforms or templates

If your site uses this plugin and it hasn’t been updated in the past few weeks, you’re likely at risk.

What Happens If You Don’t Update

Leaving the plugin outdated is risky. Attackers can take full control of your site and wreak havoc. Here’s what could go wrong:

• Full site access: Hackers gain admin control and lock you out
• Malware injection: Visitors get redirected to shady third-party pages
• Stolen data: Customer info, form entries, and payment details get exposed
• SEO hit: Google blacklists your site, causing search visibility to tank
• Lost trust: Visitors stop engaging with your site due to safety warnings

Even if everything looks fine now, an outdated plugin is an open door for hackers.

How Serious Is This Flaw

This vulnerability is ranked critically high on the CVSS scale—9.8 out of 10. That means it doesn’t require login access or special credentials to be exploited. Attackers can send one well-crafted request and hijack your site.

Security researchers have already confirmed that active exploitation is happening. Public proof-of-concept code is available, and attackers are scanning the web for vulnerable sites. The longer you delay the update, the greater the chances your site will get hit.

Steps to Update the Plugin Safely

Updating your plugin is simple and should take just a few minutes. Here’s how you can do it:

They’ve also pledged to start running routine code audits and implement faster response procedures for future reports. Their quick action helped prevent a worst-case scenario.

What the Community Thinks

The WordPress community didn’t waste time sounding the alarm. Hosting providers, forums, and security blogs spread the news fast. Some web hosts even notified users directly if the plugin was detected on their servers.

While experts appreciated the developer’s speed, many felt that the public disclosure could’ve come earlier to reduce the attack window. That said, the overall consensus is clear: update now, or risk major damage.

Security professionals also recommend setting up firewalls, monitoring plugin behavior, and conducting regular reviews of site components—not just in response to big threats, but as a routine best practice.

Conclusion

This situation proves how quickly a trusted plugin can become a major threat if left unpatched. Over a million sites were exposed, and now it’s up to users to secure their systems. The fix is available, and applying it doesn’t take long.

A site that looks fine isn’t always secure. Update the plugin and review your security settings—staying current keeps things safe and smooth.

Key takeaway: More than 1 million websites were left wide open due to this vulnerability. A patch has been released, but it won’t protect your site unless you install it. Don’t delay—update now to avoid preventable damage.

FAQs

How can I check if my site is already hacked?

Look for signs like unfamiliar admin accounts, redirects to unknown pages, spammy content, or strange files in your root directory. You can also use malware scanners like Wordfence or Sucuri to perform a full scan.

Is disabling the plugin a good temporary fix?

Disabling the plugin may reduce immediate risk, but it doesn’t solve the core problem. The safest approach is to update to the latest version or remove the plugin if you don’t use it.

What if I’m using a theme that bundles the plugin?

Themes sometimes include plugins automatically. In that case, check your theme documentation or contact the developer for guidance. You may need to install the plugin separately to access the updated version.

Will deleting the plugin break my site?

If the plugin controls key features like forms or payments, removing it could break your site. Always test on a staging site first.

Can I switch to another plugin instead?

Yes, but choose carefully. Research alternative plugins for security, compatibility, and feature set. Always test the replacement before activating it on your live site.
