What the vulnerability does
The tagDiv Composer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.3. This is due to missing or incorrect nonce validation within the td_ajax_get_views AJAX action. This makes it possible for unauthenticated attackers to inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
tagDiv Composer versions 5.3 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages. The vulnerability requires user interaction—typically clicking a malicious link—and can affect other users viewing the compromised content. An attacker with no authentication can exploit this to steal session cookies, redirect users, or deface page content.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they visit affected pages.
Potential impact on your site
Visitors' browsers can be compromised, leading to credential theft, malware distribution, or site defacement.
Conditions required to exploit
Victim must click a malicious link or visit a page containing the attacker's payload; no authentication required.
