Input validation vulnerability in Just Writing Statistics 4.7

The Just Writing Statistics plugin for WordPress has a security issue that can allow hackers to access sensitive information. This is because the plugin did not properly protect against SQL Injection, which is a type of attack that involves inserting malicious code into a website’s database. This vulnerability affects versions up to 4.7, and allows attackers with administrator-level access to add their own SQL queries to the existing ones, potentially extracting private information.
