LXD Custom Storage Volume Auth Bypass (5.0.0-5.0.10, 5.21.8, 6.10)
CVE-2026-97335 Published on September 28, 2026
Incorrect authorization in LXD storage volume API allows reading volumes from other projects
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.
