TIMELINE Jul 16 Reserved by canonical Aug 12 Published (CNA: canonical) Sep 11 EXPLOIT PUBLISHED — CVE-2026-63297 (Canonical LXD). Public exploit reference added.
An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can exploit this flaw to copy instances with disallowed high-privilege configurations into restricted projects, bypassing security controls.
