📄 Description (English)

The Zypento Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Table of Contents block in all versions up to, and including, 1.0.6. This is due to the front-end TOC rendering script reading heading text via `innerText` and inserting it into the page using `innerHTML` without proper sanitization. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

🤖 AI Executive Summary

The Zypento Blocks WordPress plugin versions up to 1.0.6 contains a Stored Cross-Site Scripting vulnerability in the Table of Contents block that allows authenticated authors to inject malicious scripts. These scripts execute when users view affected pages, potentially compromising user sessions and data.
