Critical Security Flaw in LiteSpeed cPanel Plugin Could Let Hackers Take Over Your Server

A serious security weakness has been found in the LiteSpeed User-End cPanel Plugin that could allow attackers to gain full control of affected servers. This flaw is actively being exploited, meaning hackers are already using it to run harmful commands as the highest-level user.

24 May 2026

Reference: CVE-2026-48172

1. What is being reported?

The LiteSpeed User-End cPanel Plugin, a tool used to manage web hosting servers, has a critical vulnerability that lets attackers escalate their access privileges, potentially gaining full control of the server. This happens because of a problem with how the plugin handles enabling or disabling a feature called Redis. The issue affects versions before 2.4.5, and attackers are already exploiting it in the wild.

2. What this means in plain English

If your organisation uses this plugin on your web hosting server, hackers could exploit this flaw to take over your server completely. This could lead to data theft, website defacement, or your server being used to attack others. Even if you do not manage your own server, if your hosting provider uses this plugin, your services could be at risk.

3. Could this affect a small business?

Small businesses that use web hosting services with LiteSpeed cPanel Plugin versions before 2.4.5 could be affected. If you do not use this plugin or your hosting provider has already updated it, you are unlikely to be impacted. It is important to check with your IT provider or hosting company.

4. What to do now

  • Check if your web hosting server uses the LiteSpeed User-End cPanel Plugin and confirm its version.
  • If you have access, run the recommended command to detect signs of exploitation or ask your IT provider to do so.
  • Ensure the plugin is updated to version 2.4.7 or later, as this fixes the vulnerability.
  • Review your server logs for any suspicious activity and block any unknown IP addresses found exploiting this issue.

5. Ask your IT provider

Can you confirm whether our web hosting uses the LiteSpeed User-End cPanel Plugin, and if so, has it been updated to version 2.4.7 or later to address the recent critical vulnerability CVE-2026-48172?

6. Bottom line

If you use or rely on LiteSpeed cPanel Plugin, act quickly to check and update it to prevent hackers from taking control of your server.
