Service Advisory: cPanel Security Update In Progress per CVE: CVE-2026-41940

Incident Report for Adeptcore, Inc.

Monitoring

In response to a critical cPanel vulnerability (CVE-2026-41940) disclosed by the vendor, we are proactively patching all cPanel servers across our environment.

As a precaution while updates are rolling out, public access to the cPanel/WHM/Webmail management ports (2083, 2087, 2095, 2096) has been temporarily restricted. Your websites, email, and other services are not affected only the browser-based management interfaces.
If you need access to cPanel or WHM during this window. Please submit a support request if you require access and we can setup a custom whitelist for you in the meantime.

We expect all servers to be patched and normal access restored within the next 48–72 hours. We'll send a follow-up once the work is complete.
Thank you for your patience.
