CVE-2026-5828Public exploitNetwork attack vector

Unauthenticated database access via unsanitized postid parameter

Published Apr 9, 2026 · Updated Apr 9, 2026

SQL injection in Simple IT Discussion Forum 1.0 allows remote attackers to access or alter database data through the postid parameter. The /functions/addcomment.php handler places postid directly into an SQL query without validation, escaping, or parameter binding. No authentication is required; published boolean-based and time-based payloads demonstrate database inference and query delay, while broader host compromise is not established.
