The WP Duplicate WordPress plugin through 1.1.11 does not properly verify a request authentication value and does not validate the path or type of uploaded files, making it possible for unauthenticated attackers to write arbitrary files to the server and achieve remote code execution. This vulnerability is being actively exploited in the wild.
