SQL Injection in Flightphp Core
CVE-2026-42550
Flight is an extensible micro-framework for PHP. Prior to 3.18.1, SimplePdo::insert(), SimplePdo::update(), and SimplePdo::delete() build SQL statements by concatenating the $table argument and the keys of the $data array directly into the query, with no identifier quoting and no validation. When an application forwards user-controlled data shapes to these helpers — a common and documented pattern, e.g. $db->insert('users', $request->data->getData()) — an attacker can inject arbitrary SQL by crafting malicious array keys. This vulnerability is fixed in 3.18.1.
