Title
Kadence Blocks <= 3.7.5 - Authenticated (Contributor+) Sensitive Information Exposure via Block Editor proData Localization
Summary
The Kadence Blocks — Page Builder Toolkit for Gutenberg Editor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.7.5 via the editor_assets_variables. This makes it possible for authenticated attackers, with contributor-level access and above, to extract the site's connected Kadence account license key, license owner email, api_key, api_email, and license domain from the browser console by inspecting window.kadence_blocks_params.proData. Exploitation requires only that an administrator has previously connected a valid Kadence license; the full credential bundle is then readable by any Contributor-level user from the block editor client context without any server-side request manipulation.
Severity
