What this means

ShopEngine Gutenberg WooCommerce Builder Blocks Addon before 2.4.4 is vulnerable to stored XSS, allowing contributor+ users to inject scripts into posts. The weakness is due to improper input validation and escaping. This can lead to arbitrary script execution when a higher-privileged user edits the post.

Original source description

Read the full publisher description

The ShopEngine Gutenberg WooCommerce Builder Blocks Addon WordPress plugin before 2.4.4 does not validate the user's capabilities or the ownership of the targeted post in one of its AJAX actions, and does not escape the stored value before outputting it in a JavaScript context, allowing users with a role as low as contributor to inject arbitrary scripts into any post that will run when a higher privileged user edits it.
