Descriptions

A flaw was found in openshift-logging LokiStack. The key used for caching is just the token, which is too broad. This issue allows a user with a token valid for one action to execute other actions as long as the authorization allowing the original action is still cached.

Se encontró una falla en Openshift-logging LokiStack. La clave utilizada para el almacenamiento en caché es solo el token, que es demasiado amplio. Este problema permite a un usuario con un token válido para una acción ejecutar otras acciones siempre que la autorización que permite la acción original todavía esté almacenada en caché.
