CVE-2026-71237Network attack vectorHinoki check available

Unauthenticated SQL injection via raw login query

Published Aug 5, 2026 · Updated Aug 5, 2026

SQL injection in IoT-PHP 0 allows remote attackers to bypass authentication and read database data through the /userlogin route. In index.php, the /userlogin handler reads $_POST['pwd'] and interpolates it into a mysql_query string without quoting or parameterization. No account is required; a crafted password changes the query's logic, allowing login bypass and database disclosure through UNION-based injection.
