Descriptions

Discourse is an open source platform for community discussion. Prior to version 2.8.4 on the `stable` branch and 2.9.0beta5 on the `beta` and `tests-passed` branches, inviting users on sites that use single sign-on could bypass the `must_approve_users` check and invites by staff are always approved automatically. The issue is patched in Discourse version 2.8.4 on the `stable` branch and version `2.9.0.beta5` on the `beta` and `tests-passed` branches. As a workaround, disable invites or increase `min_trust_level_to_allow_invite` to reduce the attack surface to more trusted users.

Discourse es una plataforma de código abierto para el debate comunitario. En versiones anteriores a 2.8.4 en la rama "stable" y de la 2.9.0beta5 en las ramas "beta" y "tests-passed", invitar a usuarios en sitios que usan el inicio de sesión único podía omitir la comprobación "must_approve_users" y las invitaciones del personal siempre son aprobadas automáticamente. El problema está parcheado en la versión 2.8.4 de Discourse en la rama "stable" y en versión "2.9.0.beta5" en las ramas "beta" y "tests-passed". Como mitigación, deshabilite las invitaciones o aumente "min_trust_level_to_allow_invite" para reducir la superficie de ataque a los usuarios de mayor confianza
