Input validation vulnerability in tagDiv Composer 5.3

The TagDiv Composer plugin for WordPress has a vulnerability that allows attackers to create a PHP object, which may give them access to sensitive information or the ability to execute code on the website. This vulnerability affects all versions of the plugin up to 5.3, and can be exploited without authentication. However, it only poses a risk if another plugin or theme with a specific code sequence is also installed on the website.
