2nd Revision impact statement
Title: Incorrect Audit IDs in Keystone Fernet Tokens can result in revocation bypass
Reporter: Lance Bragstad (Rackspace)
Products: OpenStack Kesytone
Affects: >=9.0.0
Description:
Lance Bragstad (Rackspace) reported a vulnerability in the Keystone Fernet Token Provider. By rescoping a token a user will receive a new token without correct audit_ids, these incorrect audit_ids will prevent the entire chain of tokens from being revoked properly. This vulnerability does not impact revoking a token by it's individual audit_id. Only deployments with Keystone configured to use Fernet tokens are impacted.
