CVE-2026-14498: CWE-434 Unrestricted Upload of File with Dangerous Type in daggerhart Query Wrangler
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.
AI Analysis
Technical Summary
CVE-2026-14498 is a remote code execution vulnerability in the Query Wrangler WordPress plugin affecting all versions up to and including 1.5.57. The flaw arises from the lack of capability checks and nonce verification on the wp_ajax_qw_form_ajax handler. Unsanitized attacker-controlled 'options' parameters fully replace saved query options and are passed directly to call_user_func_array(), guarded only by function_exists(). This allows authenticated attackers with subscriber-level privileges or higher to execute arbitrary code on the server. The vulnerability requires at least one query row in the database, with query_id being a small enumerable integer lacking access control.
Potential Impact
Successful exploitation allows an authenticated user with minimal privileges (subscriber-level or above) to execute arbitrary code on the server hosting the WordPress site. This can lead to full compromise of the affected system, including confidentiality, integrity, and availability impacts as reflected by the CVSS score of 8.8 (high severity).
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict subscriber-level user access and monitor for suspicious activity related to the Query Wrangler plugin. Avoid using the plugin if possible or disable it until a patch is released.
