CVE-2025-0928

What is CVE-2025-0928?

In certain versions of the Juju orchestration tool, authenticated controller users could upload arbitrary agent binaries to any model or the controller itself.

The vulnerability arises from a lack of verification on model membership and permission checks, enabling attackers to exploit this weakness effectively.
