CVE-2026-97335 Details
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.
A vulnerability in Canonical LXD has been identified, allowing an authenticated client to bypass project isolation when creating custom storage volumes. This issue affects LXD versions 5.0.0 and later, prior to 5.0.10, 5.21.8 and 6.10. The vulnerability arises because the custom volume creation endpoint does not properly validate authorization when the source type is omitted. As a result, a client with permission to create custom volumes can copy and access any custom storage volume from other projects on the server, including its snapshots and configuration.
Users can upgrade to Canonical LXD versions 5.0.10, 5.21.8 or 6.10 to address this vulnerability.
