CVE-2025-26186Public exploitNetwork attack vector

Unauthenticated code execution via injectable id parameter

Published Jul 15, 2025 · Updated Jul 15, 2025

SQL injection in Ajax.php in OS4ED openSIS 9.1 allows remote attackers to execute arbitrary code through the id parameter. The GenerateApi.php removal route passes the attacker-controlled id into a database query without neutralizing SQL syntax, and an appended quote produces a database error. No authentication or user interaction is required, and successful exploitation executes code in the openSIS server context.
