  - When the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete
    entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quoted only
    for the shell, not for PowerShell. A crafted entry name can break out of the intended string context and cause
    PowerShell to execute arbitrary commands with the privileges of the user running Vim, triggered by opening,
    viewing or extracting the archive. (CVE-2026-57453)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
