Wp Fastest Cache Wordpress Cache Plugin
Monthly
Stored Cross-Site Scripting in WP Fastest Cache (WordPress plugin, all versions through 1.5.0) allows unauthenticated remote attackers to inject persistent JavaScript by supplying a crafted HTTP Host header that the plugin writes into shared page-cache files, which are then served to all subsequent visitors. Exploitation requires two co-present non-default conditions: the Polylang or Polylang Pro multilingual plugin must be installed and active, and the 'Combine JS' option must be enabled in WP Fastest Cache settings, both of which activate the vulnerable Host-header-to-URL code path in js-utilities.php. No public exploit code or CISA KEV listing has been identified at time of analysis.
