The manipulation of the argument steps[].text with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. The summary by CVE is:

The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'steps[].text' parameter in all versions up to, and including, 3.7.0 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. Because wp_kses_post() preserves block-delimiter HTML comments verbatim on save, a Contributor can embed event-handler payloads inside the block's steps[].text attribute in a draft or pending post without the unfiltered_html capability, and the payload executes for any visitor — including privileged editors and administrators who preview or publish the post — as well as through the public print endpoint.
