Input validation vulnerability in NHR Options Table Manager 1.1.2

The NHR Options Table Manager plugin for WordPress has a security vulnerability that allows attackers with Administrator-level access and above to inject a PHP Object. This can only occur if the site has another plugin or theme installed that contains a specific type of code called a POP chain. Without this code, the vulnerability has no impact. If the attacker is able to access the site through a POP chain, they may be able to perform actions like deleting files, retrieving sensitive information, or executing code.
