Description
The MinhNhut Link Gateway plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'linkgate' shortcode in all versions up to, and including, 3.6.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.

Executive Summary

The MinhNhut Link Gateway plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its 'linkgate' shortcode. This vulnerability exists in all versions up to and including 3.6.1 because the plugin does not properly sanitize or escape user-supplied attributes. As a result, authenticated users with Contributor-level access or higher can inject malicious web scripts into pages. These scripts will execute whenever any user accesses the infected page.

Impact Analysis

This vulnerability allows attackers with Contributor-level access or above to inject arbitrary scripts into web pages. These scripts can execute in the context of other users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions. The impact includes loss of data confidentiality and integrity, as well as potential compromise of user accounts.
