Descriptions

Users are able to read group conversations without actively taking part in them. Next to one to one conversations, users are able to start group conversations with multiple users. It was found possible to obtain the contents of these group conversations without being part of it. This could lead to information leakage where confidential information discussed in private groups is read by other users without the users knowledge.

Los usuarios pueden leer las conversaciones de grupo sin participar activamente en ellas. Además de las conversaciones uno a uno, los usuarios pueden iniciar conversaciones de grupo con varios usuarios. Se ha detectado que es posible obtener el contenido de estas conversaciones de grupo sin formar parte de ellas. Esto podría conllevar a un filtrado de información en la que la información confidencial que se discute en los grupos privados es leída por otros usuarios sin que éstos lo sepan
