Is ISL Online down?

Update on the recent PHP vulnerabilities You may have seen news about two newly disclosed critical vulnerabilities in PHP (CVE-2026-109618 and CVE-2026-109619). Here's an update on how they relate to ISL Online. The ISL Online product is not affected. ISL Light, ISL AlwaysOn and the ISL Online servers that carry remote-support sessions do not use PHP. All services are running normally, with no interruption. ISL Online website: PHP is used only on our public website and licensing web servers, which handle the website, the account portal and the shop. Before a fix was available, we locked down the firewalls on those servers so that only Cloudflare and our own infrastructure can reach them. As soon as the security update for our server platform was released, we applied it to all of these servers within an hour. The website stayed available throughout. No action is needed on your end. Your sessions, devices and settings are not affected, and you don't need to update anything.

We have identified the root cause of the issue affecting some ISL Online Cloud users with the Ctrl+Alt+Del shortcut not working during remote sessions. This is caused by a recent update to how our ISL applications interact with the Windows Secure Attention Sequence (SAS) API. The interaction stops working when SAS is enabled, but the application allowed to generate SAS is set to None in the system policy. This issue only affects the latest version, 5.0.2551.150 (https://help.islonline.com/20067/502551147). As a workaround, affected users can either use the previous version of the ISL applications, or enable SAS generation on the remote computer by setting the policy to either "Ease of Access applications" or "Services and Ease of Access applications". Our team is working to develop and implement a solution as quickly as possible. We apologize for any inconvenience this may cause and will continue to provide updates on our progress.

We have implemented a solution to the issue affecting some ISL Online Cloud users with the Ctrl+Alt+Del shortcut not working during remote sessions. A fix is included in ISL AlwaysOn, ISL Light, and ISL Light Client version 5.0.2551.156 for Desktop, now available for hosted service users in all countries except Japan. We recommend updating to this version as soon as possible: https://help.islonline.com/20067/502551147 Our team is continuing to closely monitor the situation. We apologize for any inconvenience this may have caused and will continue to provide updates on the situation.

We have resolved the issue affecting some ISL Online Cloud users with the Ctrl+Alt+Del shortcut not working during remote sessions. The fix is included in ISL AlwaysOn, ISL Light, and ISL Light Client version 5.0.2551.156 for Desktop. The service is fully operational, and our team is continuing to monitor the situation to ensure that there are no further issues. We apologize for any inconvenience this may have caused and appreciate your patience during this time.

We have resolved the issue affecting ISL Online Cloud users with the delivery of two-factor authentication (2FA) login tokens by email, which prevented affected users from logging in. The issue was caused by a temporary email delivery problem at our email delivery provider and has since been resolved. The service is fully operational, and our team is continuing to monitor the situation to ensure that there are no further issues. We apologize for any inconvenience this may have caused and appreciate your patience during this time.
