cPanel Servers - Network Restriction in Effect

29-04-2026

cPanel has disclosed a critical vulnerability affecting cPanel/WHM login authentication. Details are available in the official advisory here:
https://support.cpanel.net/hc/en-us/articles/40073787579671-Critical-Vulnerability-with-cPanel-WHM-Login-Authentication

To protect your server and data until cPanel releases a patch, data center teams at Mumbai and Pune have restricted the following ports:

- 2082 / 2083 — cPanel (HTTP / HTTPS)
- 2086 / 2087 — WHM (HTTP / HTTPS)
- 2095 / 2096 — Webmail (HTTP / HTTPS)
- 2077 / 2078 — Webdisk (HTTP / HTTPS), where enabled

What this means for you:
Access to cPanel, WHM, and Webmail over these ports will be unavailable until the block is lifted. Websites, databases, and mail delivery (SMTP/IMAP/POP) hosted on your server are NOT affected and will continue to function normally.

We have already patched most servers and are working with the datacenter team to lift the restriction. In the interim, you should be able to access cPanel at cpanel.yourdomain and webmail at webmail.yourdomain
