What the vulnerability does
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.
Explanation of Vulnerability in Simple Terms
MinhNhut Link Gateway versions 3.6.1 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has scope change, meaning injected code can affect other users or components beyond the vulnerable feature. An attacker with low-level credentials can exploit this without user interaction.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers or affects site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other visitors or site operations; may lead to credential theft or malware distribution.
Conditions required to exploit
Attacker must have a low-privilege account on the site; no user interaction required.
