   Zwei kritische Sicherheitslücken in PHP, einer Programmiersprache, die von einem großen Anteil von Webanwendungen weltweit einschließlich Teamleader Focus verwendet wird, wurden am 20. Oktober veröffentlicht. Unser Engineering-Team hat sofort eine vorübergehende Minderung auf unserer Plattform eingeführt und überwacht sie genau, und wir werden den offiziellen Patch von PHP anwenden, sobald er später veröffentlicht wird. Wir haben derzeit keinen Hinweis darauf, dass Kundenkonten oder Daten betroffen sind, und Sie müssen nichts tun.

   Zwei kritische Sicherheitslücken in PHP wurden am 20. Oktober veröffentlicht. PHP ist eine Programmiersprache, die von einem großen Teil der Webanwendungen weltweit verwendet wird, einschließlich Teamleader Focus. Als zusätzliche Vorsichtsmaßnahme haben wir Teamleader Focus vorübergehend offline genommen, während wir den offiziellen Sicherheitspatch von PHP anwenden, und wir werden ihn wieder online bringen, sobald dies geschehen ist. Wir haben derzeit keinen Hinweis darauf, dass Kundenkonten oder -daten betroffen sind, und wir halten diese Seite auf dem neuesten Stand.

   Teamleader Focus ist derzeit nicht verfügbar. Wir haben es absichtlich offline genommen. Zwei kritische Sicherheitslücken wurden in PHP, der Programmiersprache hinter vielen Websites und Web-Apps weltweit, einschließlich Teamleader Focus, veröffentlicht. Um jedem Risiko einen Schritt voraus zu sein, haben wir Teamleader Focus als vorbeugende Maßnahme abgeschaltet. Uns sind keine Sicherheitsprobleme oder Missbrauch bekannt, und unser Team untersucht, um absolut sicher zu sein. Wann kommen wir zurück? Vorerst wollen wir Teamleader Focus um 19:00 Uhr wieder verfügbar machen. Wir können noch nicht bestätigen, ob das früher möglich sein wird, weil wir zuerst die notwendigen Schritte unternehmen müssen, um es sicher online zu bringen. Wir werden Sie auf dieser Seite veröffentlichen. Danke für deine Geduld und sorry für die Unannehmlichkeiten.

Vielen Dank, dass Sie mit uns auskommen, wir werden Sie hier informieren, sobald Teamleader Focus wieder verfügbar ist.

   Earlier today we took Teamleader Focus offline as a precaution. The PHP foundation had announced two critical security vulnerabilities in PHP, a technology our platform runs on, and we didn't want to wait for the official fix while exposed. The official fix was released today and we have now installed it across our platform. All services are available again. Our investigation has found no evidence that these vulnerabilities were used against Teamleader. That investigation is still ongoing, and we will update this page if anything changes. Thank you for your patience. If you notice anything unusual, please contact our support team.

   We are currently investigating an issue where tickets are not being forwarded to Teamleader Focus' Shared Inbox because of a 'block' coming from our ticketing provider. We are currently coordinating with our provider in order to solve the issue. Tickets can still be sent out from the Shared Inbox module, but replies on those tickets will not be forwarded to the Shared Inbox in Teamleader Focus. However, all the emails and replies to tickets you receive will still be in your email provider inbox, so we suggest using that to manage your emails for the time being. We will update the status page as soon as more information is available.
