CWE-863

Description

An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project security restrictions during cross-project instance migrations. When moving an instance cross-project to a different cluster member via POST /1.0/instances/{name} with migration: true, project: <target>, and target: <member>, the destination node skips all project restriction checks because the request arrives as an internal cluster notification. An attacker can exploit this to introduce disallowed instance configurations into a restricted project.

Affected configurations

• canonical lxd (>= 5.0.0 < 5.0.8) • canonical lxd (>= 5.1 < 5.21.6) • canonical lxd (>= 6.0 < 6.10)
