Details

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
4.3 (Medium)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
