Description

Incus is a system container and virtual machine manager. Prior to version 7.2.0, missing authorization checks exist for instance copying where an attacker knowing the name of a project that they don't have access to and the name of an instance in that project can copy the instance to a new project. This issue could allow an attacker to access secrets in instances they are not authorized to access. Version 7.2.0 patches the issue.
