  - Vim is an open source, command line text editor. Prior to version 9.1.1551, a path traversal issue in
    Vim's zip.vim plugin can allow overwriting of arbitrary files when opening specially crafted zip archives.
    Impact is low because this exploit requires direct user interaction. However, successfully exploitation
    can lead to overwriting sensitive files or placing executable code in privileged locations, depending on
    the permissions of the process editing the archive. The victim must edit such a file using Vim which will
    reveal the filename and the file content, a careful user may suspect some strange things going on.
    Successful exploitation could results in the ability to execute arbitrary commands on the underlying
    operating system. Version 9.1.1551 contains a patch for the vulnerability. (CVE-2025-53906)

Note that Nessus relies on the presence of the package as reported by the vendor.");
