AI-suggested

This vulnerability is fixed in Canonical LXD versions 5.0.10, 5.21.8, and 6.10. Users should upgrade to these or later versions to remediate the issue. Since this is not a cloud service, remediation requires applying the official patches provided by Canonical. No additional mitigation steps are indicated by the vendor advisory.

Description

Incorrect authorization in the custom storage volume creation endpoint in Canonical LXD versions 5.0.0 and later (fixed in 5.0.10, 5.21.8 and 6.10) on Linux allows an authenticated client with permission to create custom volumes in a project to copy, and so read, any custom storage volume from any other project on the server, including its snapshots and configuration. The client does this with a crafted request that sets a source volume and source.project but omits source.type.
