CVE-2026-73077

Published: August 14, 2026Last modified: August 18, 2026

Description

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.
