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.

CVE-2026-55622 affects Incus, a system container and virtual machine manager, in versions prior to 7.2.0. The vulnerability stems from missing authorization checks during instance copying operations. An attacker who knows the name of a project and an instance within that project—even without authorized access—can copy the instance to a different project. This unauthorized copying could expose sensitive secrets stored within those instances. The flaw represents a significant access control bypass in multi-tenant or shared container environments. Version 7.2.0 of Incus has been released to patch this issue. Users are strongly advised to upgrade to mitigate unauthorized access risks.
