There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - 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 the issue.
    (CVE-2026-48769)

  - Incus is a system container and virtual machine manager. Prior to version 7.1.0,
    `(*backend).CreateInstanceFromBackup` in `internal/server/storage/backend.go` contains a nil-pointer
    dereference that an authenticated user with permission to create instances in any project can trigger
    remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing
    denial of service to every project on that cluster member. This is a sibling of `GHSA-fwj8-62r8-8p8m`,
    `GHSA-r7w7-mmxr-47r9`, and `GHSA-x5r6-jr56-89pv` (all assigned 2026-05-04). Those patches added guards on
    adjacent fields of the same `backup/config.Config` struct; the `Volume` field on the instance-import path
    was missed. Version 7.1.0 contains an updated patch. (CVE-2026-47753)

  - Incus is a system container and virtual machine manager. Prior to version 7.2.0, a specially crafted image
    can be used to read or create/write arbitrary files on the host; possibly leading to arbitrary command
    execution. Version 7.2.0 fixes the issue. (CVE-2026-48749)

  - 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 `exec_UUID.stdout` and
    `exec_UUID.stderr` can be written to an arbitrary location where the `.stdout` file will contain arbitrary
    content. This behavior can be abused for arbitrary command execution. Version 7.2.0 contains a patch.
    (CVE-2026-48750)

  - 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 the issue.
    (CVE-2026-48751)

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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 execution.
    Version 7.1.0 patches the issue. (CVE-2026-48755)

The remote Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6373 advisory.

    Multiple security issues were discovered in LXD, a system container     and virtual machine manager, which could result in a bypass of security     restrictions or the execution of arbitrary commands.

    For the stable distribution (trixie), these problems have been fixed in     version 5.0.2+git20231211.1364ae4-9+deb13u7.

    We recommend that you upgrade your lxd packages.

    For the detailed security status of lxd please refer to     its security tracker page at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 execution.
    Version 7.1.0 patches the issue. (CVE-2026-48755)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote host is affected by the vulnerability described in GLSA-202608-23 (Incus: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Incus. Please review the CVE identifiers referenced below     for details.
