This week, a critical bug was identified in cPanel and WHM that allows attackers to gain unauthorized access to servers. This vulnerability has been confirmed as a zero-day exploit, meaning it was actively being used by hackers before a patch was made available. The developers are working on a fix, but until then, your data remains vulnerable.
Why You Should Care
