Yoast SEO < 27.2 - Contributor+ Stored XSS via 'jsonText' Block Attribute

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the the `jsonText` block attribute 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.
