Descriptions

Nextcloud talk is a self hosting messaging service. In versions prior 12.1.2 an attacker is able to control the link of a geolocation preview in the Nextcloud Talk application due to a lack of validation on the link. This could result in an open-redirect, but required user interaction. This only affected users of the Android Talk client. It is recommended that the Nextcloud Talk App is upgraded to 12.1.2. There are no known workarounds.

Nextcloud talk es un servicio de mensajería de autoalojamiento. En versiones anteriores a la 12.1.2 un atacante es capaz de controlar el enlace de una vista previa de geolocalización en la aplicación Nextcloud Talk debido a una falta de validación en el enlace. Esto podía dar lugar a una redirección abierta, pero requería la interacción del usuario. Esto sólo afectaba a los usuarios del cliente Android Talk. Se recomienda actualizar la aplicación Nextcloud Talk a la versión 12.1.2. No se presentan medidas de mitigación conocidas
