Executive Summary

The Sudoku Shortcode plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'background' parameter of the 'sudoku-sc' shortcode. This vulnerability exists in all versions up to and including 1.0.0 because the plugin does not properly sanitize input or escape output.

Authenticated users with Contributor-level access or higher can exploit this flaw to inject arbitrary web scripts into pages. These scripts will execute whenever any user accesses the affected page.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access to inject malicious scripts into web pages. These scripts can execute in the context of other users visiting the page, potentially leading to theft of user credentials, session hijacking, or unauthorized actions performed on behalf of users.

Because the attack is stored, the malicious code persists on the site and affects all users who view the infected page, increasing the risk and impact.
