Title:
A Keystone user can't perform revoke_token operation due to absence
of target in context
Status in OpenStack Identity (Keystone):
Fix Released
Bug description:
The default policy file which comes with keystone has
"["user_id:%(user_id)s"]" rule define for "identity:revoke_token" API, but to
trigger this rule the user_id should be the target.
For all the below listed APIs there is not target set, the way it happens for
API like "GET /users/{user_id}", in this case "["user_id:%(user_id)s"]" rule
never triggered and hence a legitimate user can not perform below operations
for his own token.
identity:check_token
identity:validate_token
identity:revoke_token
This issue can lead to a security vulnerability because token will
stay active till its life.
Fix: In my opinion we should use "X-Subject-Token" which is coming in
the header to derive the target for auth check.
