As of Wednesday, October 21, 2026, from approximately 12:00 PM, FlexNow will - for at least some users - be accessible only from computers located at RUB or via the RUB VPN (OpenVPN, https://noc.rub.de/web/vpn). This is because, due to a security vulnerability, RUB-IT-experts have restricted external access to most RUB websites, including FlexNow. Please see: https://news.rub.de/servicemeldungen/2026-10-21-sicherheitsluecken-php-rub-webseiten-temporaer-fuer-externen-zugriff-gesperrt. We, the administrators, are working to restore access for all users.
The security vulnerability concerns the programming language PHP. However, since FlexNow does not use PHP at all, there is no risk to the system.
