CVE-2026-62941 Incus: Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge

Incus is a system container and virtual machine manager. Prior to version 7.3.0, when copying an instance across projects, the project restriction check AllowInstanceCreation runs BEFORE the source instance's configuration is merged into the request. Dangerous configuration keys including...

CVE-2026-62313

Incus is a system container and virtual machine manager. Prior to version 7.3.0, project-level enforcement of restricted.containers.privilege=isolated can be trivially bypassed, allowing a user to create a non-isolated shared host idmap container in a project that is configured to forbid them. Th...

CVE-2026-55621

Incus , a system container and virtual machine manager, has a missing authorization check in its custom volume copy functionality prior to version 7.2.0 . An authenticated attacker who knows the name of a project they lack access to and a custom volume within that project can copy the volume to a...

CVE-2026-55621

Incus is a system container and virtual machine manager. Prior to version 7.2.0, missing authorization checks exist for custom volume copying where an attacker knowing the name of a project that they don't have access to and the name of a custom volume in that project can copy the custom volume t...

CVE-2026-48769

Incus is a system container and virtual machine manager. Prior to version 7.2.0, an arbitrary file write exists in the Incus client when a malicious image server returns a crafted Incus-Image-Hash header. This can lead to arbitrary command execution as root on the server. Version 7.2.0 patches th...

CVE-2026-48755 Incus has an argument injection in backup compression algorithm leading to AFW and ACE

Incus is a system container and virtual machine manager. Prior to version 7.1.0, improper validation of user-provided backup compression algorithm leads to argument injection in the constructed command line. This leads to an arbitrary file write on the host, possibly leading to arbitrary command...
