+title: OAuth1 request token authorize silently ignores roles parameter
+
+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.
