The Recipe Card Blocks Lite WordPress plugin before 3.6.4 does not sanitize and cast a block and shortcode attribute before concatenating it into SQL queries, allowing authenticated users with Contributor-level access or above to perform SQL injection attacks.

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 'WPZOOMHelpers::deserializeblockattributes' 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.
