CVE-2026-1688Public exploitNetwork attack vector

Unauthenticated database access via raw username query

Published Jan 30, 2026 · Updated Jan 30, 2026

SQL injection in itsourcecode.com Directory Management System 1.0 allows remote attackers to access and alter database data without authentication. /admin/index.php inserts the POST username value directly into a SQL query without validation or parameter binding, enabling time-based blind queries. The login endpoint requires no prior authorization; a crafted MySQL SLEEP expression demonstrates query control, while further impact depends on the database account's permissions.
