What the vulnerability does
The Element Pack Elementor Addons and Templates plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'marker_content' parameter in versions up to, and including, 8.1.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Element Pack for Elementor contains a stored cross-site scripting (XSS) vulnerability in versions up to 8.1.5. An authenticated user with low privileges can inject malicious scripts into the plugin's data fields. When other users view the affected content, the scripts execute in their browsers, potentially allowing the attacker to steal session tokens, modify page content, or perform actions on their behalf.
What an attacker can do
Inject and execute malicious JavaScript in the browsers of other site users.
Potential impact on your site
Compromised user accounts, defaced content, or malware distribution to site visitors via stored XSS payloads.
Conditions required to exploit
Attacker must have a low-privilege user account (e.g., contributor or subscriber) on the WordPress site.
