WP Cerber Security 9.6.11


As we wrap up 2025, we’re bringing you one final gift and it’s not a pair of socks [!🧦] . Before you head off to your holiday festivities, we have implemented multiple architectural improvements to WP Cerber to ensure your site remains resilient while you’re busy with the eggnog. In this version, we’ve focused on turning technical data into professional-grade forensic insights, making sure your server stays as quiet as a snowy night.

Better Browser Detection

Understanding the nature of incoming requests is the foundation of incident analysis. We have replaced legacy browser detection functions with a more precise User-Agent Header parser. This allows for a more effective security triage directly within the WP Cerber logs.

You will now see clear labels for the next generation of web actors:

  • AI bot & LLM scrapers: Full identification of scrapers and crawlers like GPTBot, ClaudeBot, and Applebot-Extended.
  • Verified Service Agents: Reliable detection of critical webhooks and APIs from PayPal and Stripe.
  • Automation Frameworks: Clear labeling of scripting tools such as python-requests, curl, and Wget.

By providing granular details such as specific versions for mobile platforms like iOS and Android we’ve turned WP Cerber logs into a tool for deep forensics, allowing you to identify threats with zero guesswork.

Professional-Grade Translations

We believe that a security tool should speak your language perfectly, especially during the holidays. We’ve improved our translation engine to resolve long-standing grammar issues and fragmented strings that affected non-English WordPress installations.

Our updated translation engine now follows better industry practices:

  • Natural Forms: We’ve fixed how the plugin handles quantities. Messages like “1 attempt” or “10 attempts” will now always use the correct grammar for your specific language, eliminating those small but distracting linguistic errors.
  • Cohesive Messages: We’ve overhauled how the plugin generates its text. Instead of stitching together fragments of words, the system now uses solid, complete phrases. This results in a cleaner, more professional interface throughout your dashboard.
  • Flexible Word Order: Different languages follow different rules for where words go in a sentence. Our new system allows translators to move words around freely, ensuring that a security alert in Japanese or German reads as naturally as it does in English.

Hardening Against DoS Vectors

In this version, we’ve optimized the plugin’s .htaccess rules specifically to mitigate CVE-2018-6389. This fix helps protect your site from potential Denial of Service (DoS) attacks that exploit how WordPress processes script and style loading. It’s an extra layer of defense that works quietly in the background to ensure your server remains resilient while you’re celebrating.

Getting the Details Right

For us, these updates represent a commitment to achieving a higher standard of technical precision. As this is our final release of the year, we want to wish you a peaceful and secure holiday season. We’ve done the heavy lifting so you can enjoy the fireworks 🎇 without checking your logs every five minutes 🤯

How to make WP Cerber speak your language

  1. Go to the main plugin settings and enable “Use WP Cerber’s plugin repository”.
  2. Scroll down to “Language for the plugin admin pages” and select your language from the drop-down list.
  3. Click Save Changes.

Within a few minutes, the selected language will be installed and activated. If you encounter any issues activating a new language, ensure that outgoing connections are not blocked via the WP_HTTP_BLOCK_EXTERNAL constant in your wp-config.php file. If they are, add "downloads.wpcerber.com" to the WP_ACCESSIBLE_HOSTS constant.

🧑‍🎄 Happy Holidays and a Secure New Year! 🧑‍🎄
