AI Powered Q&A
How can this vulnerability impact me? :
This vulnerability can allow attackers with Contributor-level access or higher to inject arbitrary malicious scripts into web pages. When other users visit these pages, the injected scripts execute in their browsers, potentially leading to theft of sensitive information, session hijacking, defacement, or other malicious actions. Because the vulnerability is stored, the malicious code persists on the site and affects all users who access the compromised pages.
Can you explain this vulnerability to me?
The WP Games Embed plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 0.1beta. This vulnerability arises because the plugin does not properly sanitize or escape user-supplied shortcode attributes such as 'width', 'height', 'src', 'title', 'description', 'game_url', 'main', and 'thumb'. These attributes are directly inserted into the HTML output without escaping, allowing authenticated users with Contributor-level access or higher to inject malicious scripts. These scripts then execute whenever any user views the affected page.
