Lieber Armin aka Cyberanteater, ganz herzlichen Dank für die Meldung der Reflected Cross-Site Scripting Lücke auf unseren Websites. Dank auch für die "private submission" der Lücke auf OpenBugBounty und die sehr ausführliche Erklärung zur Plattform per Mail. Dein Vorgehen hat uns geholfen das Thema intern zu erklären und umgehende Gegenmaßnahmen einzuleiten.

Es sollte mehr ethische White Hat Hacker von Deinem Kaliber geben. Nur so können wir das Netz zu einem besseren Ort machen.
