2026 hasn’t been kind to cPanel environments so far. A few serious vulnerabilities have already forced hosting providers to patch quickly, and in some cases, restrict access to WHM entirely until fixes were applied. Since cPanel & WHM is used on a massive number of shared hosting servers, even a single exploit ends up being a widespread problem pretty fast. CVE-2026-41940 — the one everyone kept talking about The main issue that stood out this year was CVE-2026-41940. It’s an authentication bypass in cPanel & WHM. In simple terms, it …
Server Security
The internet depends heavily on web servers and reverse proxies to deliver websites, APIs, and cloud applications securely and efficiently. One of the most widely used technologies in this space is NGINX, trusted by enterprises, startups, cloud providers, and DevOps teams worldwide. In May 2026, cybersecurity researchers disclosed a critical vulnerability named NGINX Rift, tracked as CVE-2026-42945. What makes this discovery especially alarming is that the flaw reportedly remained hidden inside the NGINX codebase for nearly 18 years before being identified. The vulnerability affects the ngx_http_rewrite_module and can potentially allow …
Dirty Frag: Universal Linux LPE
Dirty Frag is a vulnerability in Linux that allows an attacker to gain higher access or permissions than they are normally allowed on the system This vulnerability was disclosed earlier than planned due to an embargo break, which means information about the vulnerability was released publicly before the agreed-upon disclosure date. It’s a part of Linux kernel page cache exploits — following Dirty Pipe (2022) and Copy Fail (earlier this year). What are Linux kernel page cache exploits? The page cache in Linux is a system memory area where frequently …

This really needs your …
SYN floods have been around forever, and they’re still a major threat in Linux server security, especially for hosting providers and cPanel users. The trick is simple: attackers blast your server with a ton of TCP SYN packets, but never finish the TCP handshake. Your server ends up stuck, waiting on connections that never really start, eating up memory and connection slots until everything slows to a crawl—or just crashes. For web hosts, server administrators, and anyone running cPanel or other control panels, this means slow sites, broken services, and, …
If you manage a website, even a small one, security is something you can’t brush aside anymore. Hackers don’t care how big your site is. They just care if it’s vulnerable. And that’s where RunCloud’s built-in firewall and its bundled tools make a big difference. Instead of needing five different tools and a bunch of scripts, RunCloud ties several protection systems together — Firewalld, Fail2ban, basic site authentication, a Web Application Firewall (ModSecurity), and even advanced 6G/7G firewalls for modern threats. Let’s go through what each one does and why …
If you’ve ever had a website slow down the moment traffic picks up, you’ll know how helpless that feels. You open the dashboard, refresh the monitor, maybe even restart the service, and still, it lags. In most of those moments, the problem isn’t that your server is weak. It’s usually that PHP and your FPM pool just aren’t tuned quite right. I’ve spent a lot of long nights inside RunCloud dashboards, and over time I’ve built a habit of adjusting a few key settings whenever I launch or optimize a …
