The WordPress Popular Posts WordPress plugin is vulnerable to arbitrary file uploads due to insufficient input file type validation found in the ~/src/Image.php file which makes it possible for attackers with contributor level access and above to upload malicious files that can be used to obtain remote code execution, in versions up to and including 5.3.2.
