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

  - Cross-Site Request Forgery (CSRF) in LXD-UI in Canonical LXD versions >= 5.0 on Linux allows an attacker
    to create and start container instances without user consent via crafted HTML form submissions exploiting
    client certificate authentication. (CVE-2025-54286)

  - Template Injection in instance snapshot creation component in Canonical LXD (>= 4.0) allows an attacker
    with instance configuration permissions to read arbitrary files on the host system via specially crafted
    snapshot pattern templates using the Pongo2 template engine. (CVE-2025-54287)

  - Information Spoofing in devLXD Server in Canonical LXD versions 4.0 and above on Linux container platforms
    allows attackers with root privileges within any container to impersonate other containers and obtain
    their metadata, configuration, and device information via spoofed process names in the command line.
    (CVE-2025-54288)

  - Privilege Escalation in operations API in Canonical LXD <6.5 on multiple platforms allows attacker with
    read permissions to hijack terminal or console sessions and execute arbitrary commands via WebSocket
    connection hijacking format (CVE-2025-54289)

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6188 advisory.

    Package        : lxd     CVE ID         : CVE-2026-28384 CVE-2026-33542 CVE-2026-33897

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

    For the oldstable distribution (bookworm), these problems have been fixed     in version 5.0.2-5+deb12u4.

    For the stable distribution (trixie), these problems have been fixed in     version 5.0.2+git20231211.1364ae4-9+deb13u4.

    We recommend that you upgrade your lxd packages.

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.

  - An improper sanitization of the compression_algorithm parameter in Canonical LXD allows an authenticated,     unprivileged user to execute commands as the LXD daemon on the LXD server via API calls to the image and     backup endpoints. This issue affected LXD from 4.12 through 6.6 and was fixed in the snap versions     5.0.6-e49d9f4 (channel 5.0/stable), 5.21.4-1374f39 (channel 5.21/stable), and 6.7-1f11451 (channel 6.0     stable). The channel 4.0/stable is not affected as it contains version 4.0.10. (CVE-2026-28384)

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