The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5447 advisory.

    Multiple security issues were discovered in MediaWiki, a website engine for collaborative work, which     could result in cross-site scripting, a bypass of vandalism protections or information disclosure. For the     oldstable distribution (bullseye), these problems have been fixed in version 1:1.35.11-1~deb11u1. For the     stable distribution (bookworm), these problems have been fixed in version 1:1.39.4-1~deb12u1. We recommend     that you upgrade your mediawiki packages. For the detailed security status of mediawiki please refer to     its security tracker page at: https://security-tracker.debian.org/tracker/mediawiki

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 95dad123-180e-11ee-86ba-080027eda32c advisory.

  - guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP. Affected versions are subject to     improper header parsing. An attacker could sneak in a newline (\n) into both the header names and values.
    While the specification states that \r\n\r\n is used to terminate the header list, many servers in the     wild will also accept \n\n. This is a follow-up to CVE-2022-24775 where the fix was incomplete. The issue     has been patched in versions 1.9.1 and 2.4.5. There are no known workarounds for this vulnerability. Users     are advised to upgrade. (CVE-2023-29197)
