CVE-2025-47930

Zulip is an open-source team chat application. Starting in version 10.0 and prior to version 10.3, the "Who can create public channels" access control mechanism can be circumvented by creating a private or web-public channel, and then changing the channel privacy to public. A similar technique works for creating private channels without permission, though such a process requires either the API or modifying the HTML, as we do mark the "private" radio button as disabled in such cases. Version 10.3 contains a patch.

Summary		(es) Zulip es una aplicación de chat en equipo de código abierto. A partir de la versión 10.0 y anteriores a la 10.3, el mecanismo de control de acceso "Who can create public channels" se puede eludir creando un canal privado o público web y luego cambiando la privacidad del canal a público. Una técnica similar funciona para crear canales privados sin permiso, aunque este proceso requiere la API o modificar el HTML, ya que marcamos el botón "private" como deshabilitado en estos casos. La versión 10.3 incluye un parche.
