CVE-2026-73077

HIGH CVSS 4.0: 8.4 EPSS 0.14%
Updated Aug 11, 2026
Vim
Parameter Value
CVSS 8.4 (HIGH)
Fixed In 9.2.0839
Type CWE-78 (OS Command Injection)
Vendor Vim
Public PoC No

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.
