WordPress Starter Templates Plugin < 2.7.1 XSS Vulnerability

The WordPress plugin Starter Templates - Elementor, Gutenberg & Beaver Builder Templates is prone to a cross-site scripting (XSS) vulnerability.

On sites that also had the Elementor plugin for WordPress installed, it is possible for users with the edit_posts capability, which includes Contributor-level users, to import blocks onto any page using the astra-page-elementor-batch-process AJAX action. An attacker could craft and host a block containing malicious JavaScript on a server they controlled, and then use it to overwrite any post or page by sending an AJAX request with the action set to astra-page-elementor-batch-process and the url parameter pointed to their remotely-hosted malicious block, as well as an id parameter containing the post or page to overwrite. Any post or page that had been built with Elementor, including published pages, could be overwritten by the imported block, and the malicious JavaScript in the imported block would then be executed in the browser of any visitors to that page.

WordPress Starter Templates - Elementor, Gutenberg & Beaver Builder Templates prior to version 2.7.1.

Checks if a vulnerable version is present on the target host.
