Notification of cPanel Critical Security Vulnerability / Actions Taken Wednesday 29th April 2026 05:57:00

We are currently aware of a critical security issue affecting the cPanel control panel software. You can find out more here:

https://support.cpanel.net/hc/en-us/articles/40073787579671-Critical-Vulnerability-with-cPanel-WHM-Login-Authentication

In line with guidance issued by cPanel, we have temporarily suspended access to cPanel and WHM interfaces across our hosting platform as a precautionary measure.

What is affected:

• cPanel login (including cpanel.yourdomain.com and direct port access)
• WHM login for reseller accounts
• Webmail access via cPanel ports (webmail.yourdomain.com)

What is NOT affected:

• Your website — all sites continue to load and serve visitors normally
• Incoming and outgoing email — delivery and receipt are unaffected
• FTP access
• SSH access
• Databases

As of this e-mail, cPanel have released patches for various server versions - and we have already fully updated our shared hosting platform. We have also disabled Service Subdomains (aka Proxy Subdomains) as per the guidance.

Where it is possible, and we have access to do so, we are also attempting to update VPS servers - however all VPS customers should fully validate their installs at the earliest opportunity.

The global firewall restrictions also extend to VPS servers - we understand this may be disruptive and impede logging into your VPS, however we are taking a "safety-first" stance - especially during the overnight window.

We anticipate restoring cPanel access late morning 29/04/26 - once we have confidence that the initial cPanel patches cover off the issue.

We will update this page with further updates.

If you have any questions or concerns, then please don't hesitate to contact our support team.

We apologise for the inconvenience and thank you for your patience.
