CVE-2026-55622: CWE-284: Improper Access Control in lxc incus
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.
AI Analysis
Technical Summary
CVE-2026-55622 describes an improper access control vulnerability (CWE-284) in Incus before version 7.2.0. The vulnerability arises from missing authorization checks during the instance copying process. An attacker with knowledge of a project and instance name, but without access rights, can copy the instance to a new project, potentially exposing sensitive secrets contained within the instance. The vulnerability is patched in Incus version 7.2.0.
Potential Impact
