CyberRota Analysis
AI-GeneratedThe WP Fastest Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping, affecting all versions up to 1.5.0. This vulnerability allows unauthenticated attackers to inject malicious scripts into cached pages, which execute when users access those pages, provided the Polylang or Polylang Pro plugin is active and the Combine JS option is enabled. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of exploitation.
Original NVD Description
The WP Fastest Cache – WordPress Cache Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via HTTP Host Header in all versions up to, and including, 1.5.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Polylang or Polylang Pro plugin to be active and the Combine JS option to be enabled, as these conditions trigger the vulnerable Host-header-to-URL code path that writes attacker-controlled script src values into the shared page-cache file served to all subsequent visitors.
