Update - cPanel patches have been deployed across all eligible servers.
For a subset of systems running versions that cannot be updated, additional security protections are being implemented to allow continued access to cPanel services while maintaining necessary safeguards.
To ensure ongoing protection, cPanel service ports will remain restricted on these systems. Customers who prefer to fully restore standard access will need to update to a supported version of cPanel.
Our team will be reaching out with guidance on available options. If you have questions or need assistance, please contact Support.

Update - cPanel patches have been deployed across all eligible servers. As mitigation measures are now in place for the majority of systems, we have lifted the temporary network-level blocks that were implemented to prevent unauthorized access.
For servers ineligible for the patch, we are applying temporary protections at the server level using CSF. As part of this step, CSF rules are being implemented to restrict access to the affected ports. This approach allows access to be controlled by whitelisting trusted client IP addresses while maintaining appropriate security protections.
We strongly recommend that all customers update to the latest version of cPanel & WHM as soon as possible to ensure full protection against this vulnerability. For servers not eligible for the patch, we will be reaching out shortly with guidance on what options are available to secure your environment.
We will continue to closely monitor the situation and take any additional steps necessary to maintain system security and stability. If you need assistance with updating cPanel or have any concerns, please contact our Support team.

Update - The cPanel patch remains deployed across eligible systems, and network-level firewall restrictions for cPanel, WHM, webmail, and web disk ports are still in place at this time.
Our team is reconvening this morning to review overall progress, evaluate any remaining update exceptions, and determine the appropriate timing for safely removing these access restrictions.
We will provide additional updates as soon as more information becomes available.
We appreciate your continued patience as we work toward restoring full access. If you have any issues in the meantime, please contact our support team for assistance.

Update - cPanel has disclosed that the additional cPanel-provided services Webmail and Web Disk are impacted by this vulnerability.
Out of an abundance of caution, and based on cPanel’s current recommendation, we are implementing temporary protective changes on servers hosted on our network.
Temporary changes being implemented:
-Blocking access to ports related to cPanel services:
WHM: 2082 / 2083
cPanel: 2086 / 2087
Webmail: 2096 / 2097
Web Disk: 2077 / 2078
-Temporarily disabling cpsrvd, which is the web wrapper for cPanel web services.As a result, cPanel, WHM, Webmail, Web Disk, and related cPanel services will be inaccessible, including over Cloud VPN connections.
These changes do not impact websites, email delivery, databases, or Apache functionality.
Customers who normally access email through Webmail can still access email by using a mail client. Setup instructions are available here:
https://www.liquidweb.com/help-docs/email/mail-clients/setup-an-email-client/
These temporary restrictions will be reverted as soon as cPanel releases a patch addressing the critical vulnerabilities.
Additional information from cPanel is available here:

Update - A brief configuration issue in our Ashburn (NTT) data center caused an un-intended disruption to outbound network traffic. Customers with servers in this location may have experienced intermittent connectivity or downtime lasting approximately 10 minutes. Our team quickly identified and corrected the issue. All services have since been restored and are functioning normally.
We continue to restrict access to cPanel/WHM interfaces on ports 2082, 2083, 2086, and 2087 across our data centers until a patch is released by cPanel.
If you need assistance with any cPanel/WHM items please reach out to support through live chat or a ticket.
We will provide additional updates to this status page as more information is made available.

Investigating - We are actively responding to a critical vulnerability affecting all versions of cPanel & WHM. This vulnerability impacts the authentication process and could allow unauthorized access if left unmitigated.
More information from cPanel is available here: https://support.cpanel.net/hc/en-us/articles/40073787579671-Critical-Vulnerability-with-cPanel-WHM-Login-Authentication
Our team is working alongside vendor guidance and implementing proactive safeguards to protect environments.
As an immediate precaution, we have temporarily restricted access to cPanel/WHM interfaces on the following ports 2082, 2083, 2086, and 2087. Restricted access will remain in place until a patch is developed and deployed. This action is being taken to prevent potential unauthorized access while a permanent fix is finalized.
Impact:
-Restricting access to cPanel/WHM Ports via a network firewall block. During this time customers will not be able to login to either WHM or cPanel unless they use a Cloud VPN Connection.
-No impact to hosted websites, applications, email or services.
We are closely monitoring the official patch release from cPanel and will deploy it as quickly as possible. Once mitigations are no longer required, normal access will be restored.
Until a patch is released by cPanel customers will need to utilize a Cloud VPN connection to access WHM or cPanel, or reach out to support via live chat or ticket for assistance WHM or cPanel assistance. Instructions on how to create a Cloud VPN user can be found here: https://www.liquidweb.com/help-docs/portal/account/account-security/setting-up-your-cloud-vpn/
If you require access to cPanel and WHM please feel free to reach out to us via chat or open up a support ticket with your request and we will be happy to assist you.
No additional action is required at this time. We will provide additional updates to this status page as more information is made available.
