What the vulnerability does
The tagDiv Composer plugin for WordPress, used by the Newspaper theme, is vulnerable to Reflected Cross-Site Scripting via the ‘data’ parameter in all versions up to, and including, 5.3 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
tagDiv Composer versions 5.3 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages. An attacker can craft a malicious link or page that, when visited by a site user, executes arbitrary JavaScript in the victim's browser. This can lead to session hijacking, credential theft, or defacement. The vulnerability requires user interaction and affects the scope beyond the vulnerable component.
What an attacker can do
Inject and execute malicious JavaScript in a user's browser to steal session tokens, credentials, or deface the site.
Potential impact on your site
Visitors to your site could have their sessions hijacked or credentials stolen if they interact with malicious content.
Conditions required to exploit
A site user must visit an attacker-controlled link or page that triggers the vulnerability.
