The BerqWP – Automated All-In-One Page Speed Optimization for Core Web Vitals, Cache, CDN, Images, CSS, and JavaScript plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation via the store_javascript_cache.php file in all versions up to, and including, 2.2.42. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
