Description

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.
