      "value": "Discourse is an open source platform for community discussion. In affected versions maliciously crafted requests could lead to remote code execution. This resulted from a lack of validation in subscribe_url values. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. To workaround the issue without updating, requests with a path starting /webhooks/aws path could be blocked at an upstream proxy."

En las versiones afectadas, las peticiones dise\u00f1adas de forma maliciosa pod\u00edan conllevar a una ejecuci\u00f3n de c\u00f3digo remota . Esto se deb\u00eda a una falta de comprobaci\u00f3n en los valores de subscribe_url. Este problema est\u00e1 parcheado en las \u00faltimas versiones estables, beta y de prueba de Discourse. Para solucionar el problema sin necesidad de actualizar, las peticiones con una ruta que empiece por /webhooks/aws podr\u00edan bloquearse en un proxy de subida"
