Key Features
LiteSpeed Cache combines page caching with image, CSS, and JavaScript optimization tools. Its general optimization features can work across several server types, while server-level caching relies on LiteSpeed technology. The plugin also supports WordPress Multisite and common site components. These capabilities place cache rules, exclusion lists, optimized files, and administrator controls inside the normal request and rendering path.
Security Assurance
The CleanTalk Plugin Security Certification evaluation examined access control around performance settings, handling of request-derived cache inputs, output escaping in administrator and public views, and the integrity of generated resources. Special attention covered cache variation, purge actions, image and asset optimization requests, and the boundary between public traffic and privileged maintenance controls.
The plugin has been successfully tested for:
✅ Information Leakage Vulnerabilities
✅ SQL Injection Vulnerabilities
✅ Cross-Site Scripting (XSS) Attacks
✅ Cross-Site Request Forgery (CSRF) Attacks
✅ Authentication and Authentication Bypass Vulnerabilities
