Descriptions

Discourse is an open source discussion platform. Under certain conditions, a logged in user can redeem an invite with an email that either doesn't match the invite's email or does not adhere to the email domain restriction of an invite link. The impact of this flaw is aggravated when the invite has been configured to add the user that accepts the invite into restricted groups. Once a user has been incorrectly added to a restricted group, the user may then be able to view content which that are restricted to the respective group. Users are advised to upgrade to the current stable releases. There are no known workarounds to this issue.

Discourse es una plataforma de debate de código abierto. Bajo determinadas condiciones, un usuario conectado puede canjear una invitación con un correo electrónico que o bien no coincide con el correo electrónico de la invitación o no es adherido a la restricción de dominio de correo electrónico de un enlace de invitación. El impacto de este fallo es agravado cuando la invitación ha sido configurada para añadir al usuario que acepta la invitación a grupos restringidos. Una vez que un usuario ha sido añadido incorrectamente a un grupo restringido, el usuario puede entonces ser capaz de visualizar contenidos que están restringidos al grupo respectivo. Es recomendado a usuarios actualizar a versiones estables actuales. No se presentan mitigaciones conocidas para este problema
