Input validation vulnerability in WPQuiz 0.4.2

  • Severity: medium-risk
  • Status: Open
  • Publication: July 3, 2025

The WPQuiz plugin for WordPress has a security issue that allows hackers to access sensitive information through the ‘id’ attribute of the ‘wpquiz’ shortcode. This vulnerability exists in all versions up to and including 0.4.2 due to the lack of proper protection on user input and inadequate preparation in the SQL query. This means that attackers with Contributor-level access or higher can add their own queries to the existing ones, potentially retrieving private data from the database.
