Summary
The Query Wrangler plugin for WordPress up to version 1.5.57 contains a remote code execution vulnerability. Missing capability check and nonce verification in the AJAX handler allow authenticated attackers with Subscriber-level access to execute code on the server.
Risk Assessment
An attacker with minimal privileges can execute arbitrary code on the server, leading to full site compromise and potentially the entire server.
Recommendation
Update the plugin to the latest patched version. Additionally, restrict Subscriber privileges and monitor AJAX requests to the qw_form_ajax handler.
Original NVD description (English source)
The Query Wrangler plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.5.57 via the 'options' parameter parameter. This is due to missing capability check and nonce verification on the wp_ajax_qw_form_ajax handler, combined with unsanitized attacker-controlled options fully replacing saved query options and being passed directly to call_user_func_array() guarded only by function_exists(). This makes it possible for authenticated attackers, with subscriber-level access and above, to execute code on the server. Exploitation requires only that at least one query row exists in the database, as the query_id is a small enumerable integer with no further access control.
