Descriptions

Discourse is an open-source discussion platform. Prior to version 2.8.4 in the `stable` branch and version `2.9.0.beta5` in the `beta` and `tests-passed` branches, banner topic data is exposed on login-required sites. This issue is patched in version 2.8.4 in the `stable` branch and version `2.9.0.beta5` in the `beta` and `tests-passed` branches of Discourse. As a workaround, one may disable banners.

Discourse es una plataforma de discusión de código abierto. En versiones anteriores a 2.8.4 en la rama "stable" y la versión "2.9.0.beta5" en las ramas "beta" y "tests-passed", los datos de los temas de los banners están expuestos en los sitios que requieren inicio de sesión. Este problema ha sido corregido en versión 2.8.4 de la rama "stable" y en la versión "2.9.0.beta5" de las ramas "beta" y "tests-passed" de Discourse. Como mitigación, pueden deshabllitarse los banners
