LXD vulnerability

What happened

An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project restrictions during instance migration. When migrating an instance to a target project, LXD accepts configuration overrides without validating the new configuration against the target project's enforced restrictions. An attacker can exploit this flaw to move instances with disallowed high-privilege configurations into restricted projects, bypassing security controls.

Affected versions

LXD: 5.0.0 through before 5.0.8 (semver); 5.21.0 through before 5.21.6 (semver); 6.0 through before 6.10 (semver) Fixed: See vendor advisory.
