AI-Generated

An authorization bypass vulnerability in LXD allows authenticated attackers to exploit a timing flaw during configuration merging, enabling them to circumvent project restrictions when copying instances across projects. This critical flaw can lead to the unauthorized transfer of high-privilege configurations into restricted projects, undermining security controls. Organizations using LXD should prioritize remediation efforts to mitigate the risk of privilege escalation and unauthorized access.

Original NVD Description

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.
