    High [CVE-2026-73077] Arbitrary Code Execution via Insecure Shell Command Handling

    CVE-2026-73077Source published Source updated

    Vim is an open source, command line text editor. Prior to 9.2.0839, 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. This issue is fixed in version 9.2.0839. A vulnerability in Vim's shell script plugins (sh.vim, zsh.vim, ps1.vim) allows arbitrary code execution if a user selects maliciously crafted text in Visual mode and triggers a keyword lookup, due to…

    Mitigation guidance
    • To mitigate this vulnerability, users can disable the `keywordprg` option for shell script filetypes. This prevents Vim from executing external commands via the `K` command with potentially untrusted input. Create or edit the following files in your Vim configuration directory: - `~/.vim/after/ftplugin/sh.vim`: `setlocal keywordprg=` - `~/.vim/after/ftplugin/zsh.vim`: `setlocal keywordprg=` - `~/.vim/after/ftplugin/ps1.vim`: `setlocal keywordprg=` This change takes effect the next time a shell script is opened in Vim.
