A Improper Neutralization of Argument Delimiters vulnerability in Foomuuri can lead to integrity loss of the firewall configuration or further unspecified impact by manipulating the JSON configuration passed to `nft`. This issue affects Foomuuri: from ? before 0.31.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-429edf2dcf advisory.

    Upstream update to v0.31 with fixes to CVE-2025-67603 and CVE-2025-67858.

    * CVE-2025-67603: Add PolicyKit authorization to D-Bus methods.
    * CVE-2025-67858: Verify `interface` input parameter on D-Bus methods.
    * Security hardening:
      * Add `ProtectSystem=full` to all systemd service files. This changes `/etc`         to read-only for all Foomuuri processes. Make sure you don't write any         state files there in your startup hook or Foomuuri Monitor event hook.
      * Change umask to 022 when using `--fork` to fork as a background daemon         process.
      * More strict IP address verify for iplist entries.
