What the vulnerability does
The Post Grid Master plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘argsArray['read_more_text']’ parameter in all versions up to, and including, 3.4.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
Post Grid Master versions up to 3.4.13 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into the site. An attacker can craft a malicious link that, when clicked by a site visitor, executes JavaScript in the victim's browser. This can lead to session hijacking, credential theft, or defacement. The vulnerability affects the plugin's AJAX filtering functionality.
What an attacker can do
Inject and execute malicious JavaScript in visitors' browsers via a crafted link.
Potential impact on your site
Visitors' sessions and credentials can be compromised; site content can be modified or defaced in their browsers.
Conditions required to exploit
A site visitor must click an attacker-supplied link or visit a page containing the malicious payload.
