"The remote host has an application installed that is missing security updates. It is,
therefore, affected by multiple vulnerabilities:

  - Improper encoding or escaping of output in Visual Studio Code allows an unauthorized attacker to execute
    code over a network. (CVE-2026-102235)

  - Improper limitation of a pathname to a restricted directory ('path traversal') in Visual Studio Code
    allows an unauthorized attacker to execute code over a network. (CVE-2026-102238)

  - Improper neutralization of special elements used in a command ('command injection') in Visual Studio Code
    allows an unauthorized attacker to execute code over a network. (CVE-2026-69370)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
