Stored catalog record

Source record retrieved 2026-10-28T10:18:40.384245+00:00. Scheduled imports handle updates; this page does not assert that the provider was queried just now.

Vulnerability overview

In Canonical LXD before 6.8, the backup import path validates project restrictions against backup/index.yaml in the supplied tar archive but creates the instance from backup/container/backup.yaml, a separate file in the same archive that is never checked against project restrictions. An authenticated remote attacker with instance-creation permission in a restricted project can craft a backup archive where backup.yaml carries restricted settings such as security.privileged=true or raw.lxc directives, bypassing all project restriction enforcement and allowing full host compromise.

Patch review priority

Critical technical severity

  • CVSS is at least 9.0; exploitation is not established by severity alone.

FIRST EPSS: 0.42% · percentile 36.5 · score date 2026-10-27.

EPSS estimates probability of exploitation in the next 30 days. It does not measure your exposure or prove exploitation. The elevated threshold is 10%; CISA KEV takes precedence. About FIRST EPSS ↗
