What is CVE-2025-6739?

The WPQuiz plugin for WordPress is susceptible to SQL Injection due to inadequate parameter escaping in the 'id' attribute of the 'wpquiz' shortcode. This vulnerability affects all versions up to and including 0.4.2. It allows authenticated attackers, with Contributor-level access and above, to inject additional SQL queries into existing queries, potentially leading to unauthorized data extraction from the database.
