Input validation vulnerability in Premium Packages – Sell Digital Products Securely 5.9.6

The Premium Packages plugin for WordPress has a security issue called SQL Injection, which affects versions up to 5.9.6. This happens because the plugin does not properly handle certain user inputs and does not prepare the existing database queries well enough. This vulnerability allows attackers with administrator-level access to add their own malicious SQL queries to the existing ones, potentially gaining access to sensitive information from the database.
