Advisory

Source description from Wordfence Intelligence, credited to Ezekiel Victor.

The Gutentor – Gutenberg Blocks – Page Builder for Gutenberg Editor plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to 4.0.6. This is due to missing context and capability check before including post_password in REST API response data, exposing the plaintext password to any authenticated user. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve the plaintext passwords of password-protected posts via the plugin's REST endpoint.
