According to its banner, the version of Apple TV on the remote device is prior to 26.1. It is therefore affected by multiple vulnerabilities as described in the 125637

The version of Apple iOS running on the mobile device is prior to 18.7.2. It is, therefore, affected by multiple vulnerabilities.

The version of Apple iOS running on the mobile device is prior to 26.1. It is, therefore, affected by multiple vulnerabilities.

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.1. It is, therefore, affected by multiple vulnerabilities:

  - The issue was addressed with improved memory handling. This issue is fixed in macOS Tahoe 26.1. An app may     be able to cause unexpected system termination or corrupt process memory. (CVE-2025-43402)

  - Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host     nor ALL, allows listed users to execute commands on unintended machines. (CVE-2025-32462)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML     that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with     tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other     parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML     gem 3.3.6 or later include the patch to fix the vulnerability. (CVE-2024-43398)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an     XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does     not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or     later include the patch to fix the vulnerability. (CVE-2024-49761)

  - A permissions issue was addressed with improved validation. This issue is fixed in macOS Ventura 13.7.5,     iPadOS 17.7.6, macOS Sequoia 15.4, macOS Sonoma 14.7.5. A shortcut may be able to access files that are     normally inaccessible to the Shortcuts app. (CVE-2025-30465)

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