CVE-2026-63296
An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project restrictions during instance migration.
Impact
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.
