CVE-2026-85403Public exploitNetwork attack vector

Unauthenticated database manipulation via firstname SQL injection

Published Sep 4, 2026 · Updated Sep 4, 2026

SQL injection in contactus.php in Code Projects Doctor Appointment System 1.0 allows remote attackers to manipulate database queries. The handler incorporates the unauthenticated firstname form value into an SQL statement without neutralizing SQL syntax, causing injected input to become part of the query. Network access to the public contact form is sufficient; successful exploitation can read or alter application data and interrupt database-backed operations.
