  - Kea configuration and API directives can be used to overwrite arbitrary files, subject to permissions
    granted to Kea. Many common configurations run Kea as root, leave the API entry points unsecured by
    default, and/or place the control sockets in insecure paths. This issue affects Kea versions 2.4.0 through
    2.4.1, 2.6.0 through 2.6.2, and 2.7.0 through 2.7.8. (CVE-2025-32802)
