Summary

The JNews - Jeg Elementor Kit plugin for WordPress is vulnerable to unauthorized data access due to a missing capability check on the 'jkit_post_block' and 'jeg_find_author' AJAX actions in versions up to 3.2.19. Authenticated attackers with Subscriber-level access and above can enumerate all registered users and reconstruct email addresses using substring search as an oracle.

Risk Assessment

The risk includes privacy breach through exposure of user emails and usernames, potentially leading to phishing or further compromise.

Recommendation

Update the plugin to a patched version and enforce additional access controls on AJAX actions.

Original NVD description (English source)

The JNews - Jeg Elementor Kit plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on both the 'jkit_post_block' and 'jeg_find_author' AJAX actions in versions up to, and including, 3.2.19. The 'wp_ajax_jkit_post_block' handler (registered generically for every element via wp_ajax_{$element_id} in Elements_Option_Abstract::setup_hook) returns the element's full option schema — including a freshly minted wp_create_nonce('jeg_find_author') — to any authenticated caller, and the 'wp_ajax_jeg_find_author' handler then runs a WP_User_Query with the attacker-supplied 'query' wrapped in '*…*' against search_columns that include user_email, echoing the ID and display_name of every matching user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to enumerate every registered user of the site and to reconstruct arbitrary users' email addresses one character at a time by using the substring search as an oracle.
