What the vulnerability does
The Elementor Website Builder Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via widget's custom_id in all versions up to, and including, 3.20.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Elementor Website Builder Pro versions up to 3.20.1 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability affects the scope beyond the vulnerable component, meaning injected code can impact other parts of the site. An attacker with low-level site access can craft malicious input that executes in other users' browsers, potentially compromising site functionality or stealing data.
What an attacker can do
Inject malicious JavaScript that executes in other users' browsers and affects other site components.
Potential impact on your site
Authenticated users with low privileges can inject scripts affecting the entire site, risking data theft or malware distribution to visitors.
Conditions required to exploit
Attacker must have a low-privilege account on the site (e.g., contributor or editor role).
