Does this matter?

Lower severity and a low EPSS score (0.66%). Track it; it rarely justifies an emergency change on its own.

Description

The /charms endpoint on a Juju controller lacked sufficient authorization checks, allowing any user with an account on the controller to upload a charm. Uploading a malicious charm that exploits a Zip Slip vulnerability could allow an attacker to gain access to a machine running a unit through the affected charm.
