Descriptions

Discourse is an open source platform for community discussion. Versions prior to 3.0.1 (stable), 3.1.0.beta2 (beta), and 3.1.0.beta2 (tests-passed) are subject to Allocation of Resources Without Limits or Throttling. As there is no limit on data contained in a draft, a malicious user can create an arbitrarily large draft, forcing the instance to a crawl. This issue is patched in versions 3.0.1 (stable), 3.1.0.beta2 (beta), and 3.1.0.beta2 (tests-passed). There are no workarounds.

Discourse es una plataforma de código abierto para el debate comunitario. Las versiones anteriores a 3.0.1 (estable), 3.1.0.beta2 (beta) y 3.1.0.beta2 (pruebas aprobadas) están sujetas a la asignación de recursos sin límites ni limitaciones. Como no hay límite para los datos contenidos en un borrador, un usuario malintencionado puede crear un borrador arbitrariamente grande, lo que obliga a rastrear la instancia. Este problema se solucionó en las versiones 3.0.1 (estable), 3.1.0.beta2 (beta) y 3.1.0.beta2 (pruebas aprobadas). No hay soluciones.
