Summary
An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.

"value": "Se detect\u00f3 un problema en OpenStack Keystone versiones anteriores a 15.0.1 y 16.0.0. La lista de roles proporcionados para un token de acceso OAuth1 es ignorada silenciosamente. Por lo tanto, cuando es usado un token de acceso para solicitar un token de keystone, el token de keystone contiene todas las asignaciones de roles que el creador ten\u00eda para el proyecto. Esto resulta en que el token de keystone proporcionado tenga m\u00e1s asignaciones de roles que las previstas por el creador, posiblemente otorgando un acceso escalado no deseado."
