The Security & Malware scan by CleanTalk plugin for WordPress is vulnerable to arbitrary file uploads due to the plugin uploading and extracting .zip archives when scanning them for malware through the checkUploadedArchive() function in all versions up to, and including, 2.149. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
