"The version of Microsoft Visual Studio Code installed on the remote Windows host is prior to 1.123.2. It is, therefore, 
affected by multiple vulnerabilities:

  - Improper input validation in Visual Studio Code allows an unauthorized attacker to elevate privileges over
    a network. (CVE-2026-47281)

  - Improper limitation of a pathname to a restricted directory ('path traversal') in GitHub Copilot and Visual 
    Studio Code allows an unauthorized attacker to bypass a security feature locally. (CVE-2026-45482)

  - Inclusion of functionality from untrusted control sphere in Visual Studio Code allows an unauthorized 
    attacker to elevate privileges locally. (CVE-2026-47292)

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