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.

Insufficient Session Expiration in OpenStack Keystone
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.

CVE-2020-12690 [HIGH] CWE-863 openstack-keystone: OAuth1 request token authorize silently ignores roles parameter
openstack-keystone: OAuth1 request token authorize silently ignores roles parameter
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.
A flaw was found in Keystone, where it inadvertently provided OAuth1 access tokens to every role assignment the creator had for a project, resulting in giving more permissions and escalated access in role assignments than intended. The greatest impact is on confidentiality.

CVE-2020-12690 [HIGH] CVE-2020-12690 openstack-keystone: OAuth1 request token authorize silently ignores roles parameter
CVE-2020-12690 openstack-keystone: OAuth1 request token authorize silently ignores roles parameter
A vulnerability was found in Keystone's OAuth1 Token API. Previously the list of roles provided for an OAuth1 access token were ignored, so when an access token was used to request a keystone token, the keystone token would contain 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.
