What the vulnerability does
01Description
The WordPress Simple HTML Sitemap plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter in all versions up to, and including, 3.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
Explanation of Vulnerability in Simple Terms

An attacker with high-level site privileges can inject malicious SQL code to read, modify, or delete database contents. The vulnerability affects the entire database, not just the plugin's tables. No user interaction is required once the attacker has administrative access.
