CVE-2026-2199Public exploitNetwork attack vector

Unauthenticated database manipulation via unsanitized user ID

Published Feb 9, 2026 · Updated Feb 9, 2026

SQL injection in Online Reviewer System 1.0 allows remote attackers to read or alter database data through a crafted id parameter. The user-delete.php endpoint inserts the id GET parameter directly into a MySQL query without validation or parameter binding. No login is required, and public payloads demonstrate boolean-, error-, stacked-query-, and time-based database manipulation.
