CodeAstro Online Classroom CVE-2026-7196

Apply a security patch released by CodeAstro as soon as available via https://codeastro.com/. Immediate interim mitigation includes implementing input validation and parameterized prepared statements for all SQL queries, specifically in the /guestdetails endpoint handler to enforce type checking on the deleteid parameter and reject non-numeric or malformed input. Additionally, apply Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the deleteid parameter (keyword patterns: UNION, SELECT, DROP, INSERT, UPDATE, DELETE, EXEC, etc.). Restrict access to the /guestdetails endpoint to IP ranges or networks where guest detail queries are legitimately needed, reducing the attack surface. Apply the principle of least privilege to the database user account used by the application, removing or denying INSERT, UPDATE, DELETE permissions if the endpoint only reads guest details. Database-level monitoring for anomalous SQL query patterns or syntax errors should be enabled to detect exploitation attempts in real-time.
