Important Update Alert for WordPress admins: LiteSpeed Cache Plugin Fix Needed ASAP

A Cross-Site Scripting (XSS) vulnerability, officially designated as CVE-2023-40000, has been identified in the LiteSpeed Cache plugin. This flaw allows unauthorised individuals executing the script to gain complete control over your WordPress site.


The Technical Details

A vulnerability in the LiteSpeed Cache for WordPress (LSCWP) plugin, affecting versions 5.7.0.0 and earlier, potentially allows individuals without appropriate permissions to acquire admin privileges through the litespeed/v1/cdn_status endpoint.


Who’s Affected and What to Do

If you’re using a version of the LiteSpeed Cache plugin before 5.7.0.1, we strongly recommend that you upgrade to version 5.7.0.1 or newer to close this security loophole.


Upgrading Is Easy:

  1. Log in to your WordPress dashboard.
  2. Head over to the “Plugins” section.
  3. Check if Litespeed Cache is 5.7.0.1 or later. If not, click the “update now” button.
