CVE-2026-48754: NULL Pointer Dereference

Incus is a system container and virtual machine manager. Prior to version 7.1.0, backend.createDependentVolumesFromBackup in internal/server/storage/backend.go contains a cluster of unguarded pointer derefs on every dependent-volume entry's VolumeSnapshotsi, Volume, and Pool sub-fields. An...

CVE-2026-48753: External Control of File Name or Path

Incus is a system container and virtual machine manager. Prior to version 7.1.0, the S3 protocol upload endpoint is vulnerable to path traversal and allows creation of arbitrary files on the host. This behavior could lead to arbitrary command execution. Version 7.1.0 fixes the issue...

CVE-2026-48751: Missing Authorization

Incus is a system container and virtual machine manager. Prior to version 7.2.0, instance snapshots ignore the restricted.containers.lowlevel=block setting; allowing for arbitrary command execution on the Incus server by abusing lowlevel hooks such as raw.lxc and raw.qemu. Version 7.2.0 patches t...

CVE-2026-48750: External Control of File Name or Path

Incus is a system container and virtual machine manager. Prior to version 7.2.0, the record-output parameter of the /instances/$name/exec endpoint stores the output of the command in the exec-output directory of the instance. If exec-output is a symlink, file named execUUID.stdout and...
