What the vulnerability does
The RTMKit plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'themebuilder' parameter in all versions up to, and including, 1.6.8 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 site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
RTMKit versions up to 1.6.8 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 page. An attacker with no authentication can exploit this to steal session cookies, redirect users, or deface content.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they visit a crafted link.
Potential impact on your site
Users' sessions and data can be compromised; site reputation and trust may be damaged.
Conditions required to exploit
Victim must click an attacker-supplied link or visit a page containing the malicious payload.
