CVE-2026-11357Network attack vector

License credential disclosure via block editor localization

Published Jun 18, 2026 · Updated Jun 18, 2026

Information exposure in StellarWP Kadence Blocks 3.7.5 and earlier allows remote authenticated users to read connected-license data. The editor_assets_variables component places the license key, owner email, API key, API email, and domain into window.kadence_blocks_params.proData without a capability-based filter. Contributor-level access and a previously connected valid license are required; the exposed bundle provides reusable license and API credentials.
