CVE-2026-16765Public exploitNetwork attack vector

Unauthenticated database access via unsanitized aid parameter

Published Jul 23, 2026 · Updated Jul 23, 2026

SQL injection in CodeAstro Online Classroom 1.0 allows remote attackers to read or alter database data through a crafted aid parameter. The loginlinkadmin.php endpoint places the POST aid value directly into an SQL query without validation, cleaning, or parameterization. No valid account is required; the demonstrated time-based blind payload can infer data, while further effects depend on the web application's database privileges.
