Update

While we await our upstream network partners to lift the global port restrictions, we have implemented a custom access patch for our customers under the crispr server. You can now access your management panels via the following secure URLs, which bypass the currently blocked ports:

cPanel:
https://cpanel.crispr.fah-dc3-ds.com/

Webmail:
https://webmail.crispr.fah-dc3-ds.com/

WHM:
https://whm.crispr.fah-dc3-ds.com/

We are continuing to monitor the situation with our network partners and will restore standard access as soon as the port blocks are released. If you encounter any issues with these links, please reach out to our support team.

Update

We have successfully completed emergency patching across our entire infrastructure. All Fusion Arc Hosting nodes are now running the secured version of cPanel/WHM (134.0.20 or above).

Access Restoration:

Restored: Full access to cPanel, WHM, and Webmail has been restored for the majority of our network.

Pending [Crispr.fah-dc3-ds.com]: While the Crispr node itself is fully patched and secure, our Data Center partner is still maintaining a network-level block on this specific segment and server rack.

What this means for Crispr clients:
You will continue to see "Connection Timed Out" errors when trying to reach ports 2083 (cPanel), 2087 (WHM), and 2096 (Webmail). We are in active communication with the partner NOC to have this final block removed as soon as possible.

Important: All websites, databases, and standard email services on the Crispr node remain fully operational and online.

We will provide the final "All Clear" once the data center and network partner releases the port blocks for this remaining node.
Identified on 28 Apr 2026 17:54:38 (UTC-06:00)
We are currently responding to a critical authentication vulnerability affecting all versions of cPanel & WHM. This is a high-priority security event, and our team is taking immediate action to secure our infrastructure.

Our Response

Emergency Patching: We have initiated a fleet-wide update across all Fusion Arc nodes.

Proactive Mitigation: All remaining nodes are being patched as an immediate priority.

Access Restrictions
To ensure total environment safety, our NOC team has implemented temporary network-level blocks on all cPanel-related ports to prevent unauthorized exploit attempts.

Affected Ports: 2083 (cPanel), 2087 (WHM), 2096 (Webmail).

Access: Control panels and Webmail will remain inaccessible via web browsers until these blocks are lifted by our NOC.

Service Impact

Websites: ONLINE. No impact to live websites, applications, or databases.

Email: ACTIVE. Mail delivery is functioning normally. Please use local mail clients (Outlook, Apple Mail, mobile devices) to access your mail, as Webmail is temporarily restricted.

Next Steps
We are monitoring the patching progress closely. Full access will be restored the moment the network-wide blocks are lifted and all environments are confirmed secure.
