CVE-2026-86665Public exploitNetwork attack vector

Unauthenticated update action access via missing authorization

Published Sep 8, 2026 · Updated Sep 8, 2026

Missing authorization in Aircheng iWebShop 5.0 through 5.15 allows remote attackers to invoke the web-based software update action. The Update::index method in controllers/update.php exposes the updater workflow without performing an authorization check before processing a request. No credentials or user interaction are required; public sources do not identify the exact state changes or data exposed by the action.
