"The version of Vim installed on the remote host is prior to 9.2.0496. It is, therefore, affected by a vulnerability
as referenced in the GHSA-4473-94jm-w5x9 advisory.

  - A code injection vulnerability exists in s:stepmatch() in the cucumber filetype plugin
    (runtime/ftplugin/cucumber.vim) on Vim builds with +ruby support. Step-definition patterns read from .rb
    files under the repository's features/*/ or stories/*/ directories are embedded into a Ruby Kernel.eval
    argument without sufficient escaping, allowing a crafted pattern in an attacker-controlled repository to
    execute arbitrary Ruby (and through it arbitrary shell commands) when the user invokes a step-jump mapping
    ([d, ]d). (CVE-2026-47167)

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