CodeAstro Online Classroom EUVD-2026-26931

Implement input validation and parameterized queries (prepared statements with bound parameters) for all database interactions, particularly in the /OnlineClassroom/addnewstudent endpoint's fname parameter handling. Update CodeAstro Online Classroom to the latest available version and apply any security patches released by the vendor. As an interim compensating control, restrict access to the /OnlineClassroom/addnewstudent endpoint to administrative users only via network access control lists or web application firewall rules, reducing the attack surface to high-privilege accounts. Additionally, implement database-level protections such as running the application's database service under a least-privilege account with limited SELECT, INSERT, UPDATE permissions (no DROP, ALTER, or administrative rights) to contain the impact of successful SQL injection to data exfiltration and modification rather than structural database destruction. Monitor for suspicious SQL error messages in application logs and database query logs for patterns indicative of SQL injection attempts.
