Description
A flaw exists in juju related to cross-model authorization. If permissions for a charm in a cross-model relation are revoked or expire, a malicious user capable of updating database records can create an invalid macaroon. This macaroon is incorrectly validated by the juju controller, allowing the charm to retain unauthorized access to another charm’s workload, even after permissions have been revoked or expired.
