==============================================================================
OSSA-2020-005: OAuth1 request token authorize silently ignores roles
parameter
==============================================================================

:Date: May 06, 2020
:CVE: Pending


Affects
~~~~~~~
- - Keystone: <15.0.1, ==16.0.0


Description
~~~~~~~~~~~
kay reported a vulnerability in Keystone's OAuth1 Token API. The list
of roles provided for an OAuth1 access token are ignored, so when an
OAuth1 access token is used to request a keystone token, the keystone
token will contain every role assignment the creator had for the
project instead of the provided subset of roles. This results in the
provided keystone token having more role assignments than the creator
intended, possibly giving unintended escalated access.
