What the vulnerability does
The Sudoku Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'background' parameter in the 'sudoku-sc' shortcode in all versions up to, and including, 1.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Sudoku Shortcode versions 1.0.0 and earlier contain a cross-site scripting vulnerability. An attacker with low-level site access can inject malicious scripts that execute in other users' browsers, potentially stealing session tokens or modifying page content. The vulnerability affects the scope beyond the vulnerable component itself.
What an attacker can do
Inject malicious scripts that run in other users' browsers and steal data or modify site content.
Potential impact on your site
Compromised user accounts, stolen session tokens, or defaced site content if a low-privilege user is compromised.
Conditions required to exploit
Attacker must have low-level site access (e.g., contributor or subscriber role). No user interaction required.
