CVE-2026-11357: CWE-200 Exposure of Sensitive Information to an Unauthorized Actor in stellarwp Kadence Blocks — Page Builder Toolkit for Gutenberg Editor
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.
AI Analysis
Technical Summary
CVE-2026-11357 is a sensitive information exposure vulnerability (CWE-200) in the Kadence Blocks — Page Builder Toolkit for Gutenberg Editor WordPress plugin. In all versions up to and including 3.7.5, authenticated users with contributor-level permissions or higher can access sensitive license-related data (license key, license owner email, API key, API email, license domain) by inspecting the JavaScript variable window.kadence_blocks_params.proData in the browser console. This occurs because the plugin exposes these credentials client-side via editor_assets_variables once a valid license is connected by an administrator. No server-side request manipulation is required for exploitation.
Potential Impact
An attacker with contributor-level access or higher can obtain sensitive license credentials including license keys and API keys from the client-side environment. This could lead to unauthorized use or abuse of the license and associated services. The confidentiality of license-related information is compromised, but there is no indication of impact on integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and avoid connecting a valid Kadence license on sites where untrusted contributors have editor access. Monitor vendor communications for an official fix or update.
