Technical details of the security flaw in servers 🛡️

The vulnerability lies in improper handling of user input within the LiteSpeed administration module. An unauthenticated attacker can send crafted HTTP requests to overflow a buffer, enabling system-level code injection. By escalating privileges to root, the attacker can install backdoors, modify critical files, or launch attacks against other servers. It is recommended to patch or disable the plugin until further notice.

Update or say goodbye to your server, that is the question 😅

It seems some administrators believe ignoring update notifications is an extreme sport. Now, with CVE-2026-48172, the sport could be watching a script with root privileges turn your server into a private party for cybercriminals. If your cPanel starts sending emails to your grandmother asking for bitcoins, don't say we didn't warn you. Update, it's free and hurts less than an attack.
