Descriptions

Discourse is a platform for community discussion. In affected versions any private message that includes a group had its title and participating user exposed to users that do not have access to the private messages. However, access control for the private messages was not compromised as users were not able to view the posts in the leaked private message despite seeing it in their inbox. The problematic commit was reverted around 32 minutes after it was made. Users are encouraged to upgrade to the latest commit if they are running Discourse against the `tests-passed` branch.

Discourse es una plataforma de discusión comunitaria. En las versiones afectadas, cualquier mensaje privado que incluya un grupo tenía su título y el usuario participante expuestos a usuarios que no tienen acceso a los mensajes privados. Sin embargo, el control de acceso a los mensajes privados no estaba comprometido, ya que los usuarios no podían visualizar los mensajes privados filtrados a pesar de verlos en su bandeja de entrada. El commit problemático fue revertido unos 32 minutos después de su realización. Se recomienda a los usuarios que actualicen al último commit si están ejecutando Discourse con la rama "tests-passed"
