CVE-2026-14498: Query Wrangler <= 1.5.57 - Authenticated (Subscriber+) Remote Code Execution via 'options' Parameter

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 wpajaxqwformajax handler, combined with unsanitized attacker-controlled options fully replacing saved query options and being passed directly to calluserfuncarray() guarded only by functionexists(). 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 queryid is a small enumerable integer with no further access control.
