CVE-2026-3011
Deferred Deferred - Pending Action
Stored XSS in Recipe Card Blocks Lite WordPress Plugin

Publication date: 2026-06-08

Last updated on: 2026-06-08

Assigner: Wordfence

Description
The Recipe Card Blocks Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the recipe block's 'summary' and 'notes' attributes in all versions up to, and including, 3.4.13. This is due to the 'WPZOOM_Helpers::deserialize_block_attributes' method converting unicode-encoded sequences back into HTML characters after sanitization has already been applied. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that execute whenever a user accesses the published post or the print view of an injected recipe.

Executive Summary

The Recipe Card Blocks Lite plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its recipe block's 'summary' and 'notes' attributes in all versions up to and including 3.4.13.

This vulnerability arises because the method WPZOOM_Helpers::deserialize_block_attributes converts unicode-encoded sequences back into HTML characters after sanitization has already been applied, allowing malicious scripts to be injected.

Authenticated attackers with Author-level access or higher can exploit this to inject arbitrary web scripts that execute whenever a user views the published post or its print view.

Impact Analysis

This vulnerability can allow attackers with Author-level access to inject malicious scripts into posts, which will execute in the browsers of users who view those posts.

Such script execution can lead to theft of user data, session hijacking, defacement of content, or other malicious actions performed in the context of the affected website.

Because the vulnerability is a Stored Cross-Site Scripting, the malicious code persists on the site and affects all users who access the infected content.
