Critical alert in cPanel: patch your server now

Published on April 30, 2026 | Translated from Spanish

A critical authentication vulnerability has been detected in cPanel that exposes web hosting servers to unauthorized access. Administrators must apply security updates immediately. The Zscaler ThreatLabz 2026 report indicates that artificial intelligence has reduced human reaction time, making remote access the fastest path to a security breach.

The technical flaw and its potential exploitation 🔐

The vulnerability resides in cPanel's authentication module, allowing a remote attacker to bypass credential verification through manipulated HTTP requests. It requires no prior authentication and affects versions prior to patch 110.0.20. Successful exploitation grants full control over hosting accounts. It is recommended to update to the fixed version and review access logs for anomalous activity. The patching window has been drastically reduced with the automation of attacks.

AI isn't just stealing your job, it's also stealing your server access 🤖

It turns out that artificial intelligence isn't just writing poems and drawing kittens, but now it's also finding holes in your control panel faster than you can grab a coffee. The Zscaler report makes it clear: while you were updating WordPress plugins, AI was already planning how to bypass your authentication. Good thing the patch arrived before the bots set up a virtual store on your server.
