CVE-2026-2247Network attack vector

Authenticated database disclosure via id_alu SQL injection

Published Feb 17, 2026 · Updated Feb 17, 2026

SQL injection in Clickedu SaaS report generation allows remote authenticated users to read confidential database data via a crafted URL. The generated PDF URL accepts unusual characters after id_alu without neutralizing them, enabling boolean- and time-based blind SQL queries. Exploitation requires a previously authenticated session token, and the token embedded in the URL remains valid for days, extending access to confidential database information.
