CVE-2026-5412 Â (opens in a new tab)How to fix?
Upgrade github.com/juju/juju/apiserver/common to version 2.9.58, 3.6.21 or higher.
Overview
Affected versions of this package are vulnerable to Improper Authorization via the CloudSpec method on the Controller facade. An attacker can obtain sensitive cloud credentials by making an authenticated API call with only basic login permissions, without requiring elevated privileges. This is only exploitable if the attacker has login permission to a controller and knows the controller model UUID.
Workaround
This vulnerability can be mitigated by restricting ingress to the controller API port 17070 on all controller machines or the controller service.
