A critical security vulnerability affecting cPanel & WHM login authentication has recently been identified by the vendor. This issue impacts all currently supported versions of cPanel and may expose servers to unauthorized access if left unpatched.
The good news is that cPanel has now released the official security patch for supported versions. We strongly recommend that all customers using VPS and Dedicated Servers; update to the latest cPanel version at the earliest to avoid any potential impact from this vulnerability.
Action Required: Please update cPanel to the latest version via WHM or from the server using the standard update process.
No known service impact has been reported at this time. Servers with auto-updates enabled may already receive the patch automatically. Customers running older / unsupported cPanel versions are strongly advised to upgrade to a supported build immediately, as the vulnerability may also affect those versions.
We recommend applying this update as soon as possible as a precautionary security measure.
