The LiteSpeed Cache plugin, which is used on millions of WordPress sites to optimize site performance, was found to have a critical vulnerability that exposes sensitive user data. Specifically, the flaw could allow attackers to steal user session cookies and other stored data, leading to unauthorized access to accounts or more severe attacks like session hijacking.
Scope
Since WordPress powers over 40% of all websites globally, the reach of this vulnerability is extensive. Websites that fail to update the plugin are at risk of exposing their users’ personal data to attackers.
Immediate Actions
Users and administrators of WordPress sites are strongly advised to update the LiteSpeed Cache plugin to its latest version and implement additional security measures such as two-factor authentication (2FA).
