One issue would have allowed cross-tenant attacks, and another enabled access to a shared registry for container images; exploitation via an insecure Pickle file showcases emerging risks for AI-as-a-service more broadly.
### Impact Note: "Pebble" here refers to [Canonical's service manager](https://github.com/canonical/pebble), not the [Let's Encrypt ACME test server](https://github.com/letsencrypt/pebble). The API behind `pebble pull`, used to read files from the workload container by Juju charms, allows access from any user, instead of just admin. In Juju Kubernetes sidecar charms, Pebble and the charm run as root, so they have full access. But if another restricted unix user gains local access to the container host, they could hit the Pebble `GET /v1/files?action=read` API and would be allowed to read any file in the workload container, for example an ssh key or database password or other sensitive information. If there are ssh keys they could then potentially ssh into the workload, or if something like a database password they could log into the database. Note that this requires local user access to the host machine. It seems unlikely that an attacker could gain this level of access in a Juju Ku...
