Title:
Valid tokens may remain after token's user was deleted
Status in OpenStack Identity (Keystone):
Invalid
Status in OpenStack Security Advisories:
Won't Fix
Bug description:
When user is deleted, deleted user's tokens are expired after committing
transaction for deleting user.
If database dies while tokens are being expired, remaining tokens will lose
the chance to expire until 24 hours later.
(Because user is already deleted.)
In this case, remaining tokens are able to used to authenticate despite the
fact that token's user was deleted.
I think this case is dangerous from the security point of view.
