cPanel Zero-Day: 44K Servers Hacked, Millions of Websites Ransomed for 2 Months

A critical cPanel vulnerability (CVE-2026-41940) was exploited as a zero-day for 64 days, compromising over 44,000 servers and millions of websites. The Sorry ransomware gang mass-deployed encryption attacks while state actors used the same backdoor for espionage against Southeast Asian governments. With a CVSS score of 9.8, this authentication bypass flaw affected 1.5+ million internet-facing cPanel servers globally.

This web hosting security breach demonstrates how attackers are increasingly targeting trusted infrastructure rather than individual applications. The two-step exploit used CRLF injection and malformed cookies to bypass cPanel's authentication entirely, giving attackers full admin access without passwords or 2FA. If you use shared hosting, manage websites, or deploy applications to cPanel servers, this vulnerability directly impacts your security posture.

The patch (cPanel 11.126.0.6+) has been available since April 28, but millions of servers remain vulnerable due to delayed updates. Check your hosting provider's patch status immediately and audit access logs for suspicious activity since February 23.
