CVE-2026-10256Public exploitNetwork attack vector

Authenticated SQL injection via unsanitized comment name

Published Jun 1, 2026 · Updated Jun 1, 2026

SQL injection in /save_comment.php in itsourcecode.com Content Management System 1.0 allows remote authenticated users to alter SQL queries. The handler inserts the POST name value into a database query without validation or parameter binding, and the published PoC injects a MySQL SLEEP expression. All CNA vectors require low privileges despite the PoC page's contradictory unauthenticated claim; injection enables blind database reads or writes and interruption.
