CyberRota Analysis
AI-GeneratedAn improper validation vulnerability in the instancePostMigration function of LXD allows authenticated attackers with can_create_instances permissions to bypass project-level security restrictions during instance migration. This flaw enables the creation of high-privilege instances in unrestricted projects, which can then be moved to restricted projects, compromising their security. Organizations using LXD, particularly those with strict project-level access controls, should prioritize addressing this critical vulnerability to prevent potential exploitation.

Original NVD Description
An improper validation vulnerability in the instancePostMigration function in lxd/instance_post.go of LXD allows an authenticated attacker with can_create_instances permissions on a restricted project to bypass project-level security restrictions. When migrating an instance between projects, LXD fails to validate the instance's configuration against the target project's enforced restrictions (such as restricted.containers.lowlevel, restricted.devices.*, and restricted.networks.access). An attacker can exploit this by creating a disallowed or high-privilege instance in an unrestricted project and subsequently moving it into the restricted project.
