CVE-2026-97335

EUVD-2026-88259

28.09.2026, 14:17

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.

Common Weakness Enumeration

CWE-863 - Incorrect Authorization
The software performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions.
