Vim < 9.2.0839 OS Command Injection (GHSA-r5v6-q6j8-8qw2)

high Nessus Plugin ID 335163

Synopsis

A text editor installed on the remote host is affected by a command injection vulnerability.

Description

The version of Vim installed on the remote host is prior to 9.2.0839. It is, therefore, affected by a vulnerability as referenced in the GHSA-r5v6-q6j8-8qw2 advisory.

- The runtime/ftplugin/sh.vim, runtime/ftplugin/zsh.vim, and runtime/ftplugin/ps1.vim filetype plugins pass attacker-controlled Visual-mode selections from K through keywordprg commands without safely separating shell arguments. fnameescape() and PATH_ESC_CHARS do not neutralize shell metacharacters before ShKeywordPrg, ZshKeywordPrg, or GetHelp invokes bash, zsh, or PowerShell, allowing arbitrary operating-system commands to execute with the privileges of the user running Vim. (CVE-2026-73077)

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

Solution

Upgrade to Vim version 9.2.0839 or later.
