CVE-2026-73078
HighCVSS 8.6Summary
Vim, an open source command line text editor, prior to 9.2.0840 has a vulnerability in runtime/plugin/netrwPlugin.vim and runtime/pack/dist/opt/netrw/autoload/netrw.vim where Bookmarks, History, and Targets menu entries are constructed by interpolating attacker-controlled directory paths into executed :menu commands. Functions s:NetrwBookmarkMenu(), s:NetrwTgtMenu(), g:netrw_menu_escape, EX_TRLBAR, and netrw#MakeTgt() fail to neutralize the | command separator or single quotes at five construction sites, allowing a crafted path browsed or bookmarked in GUI Vim to execute arbitrary Ex and operating-system commands. The issue is fixed in version 9.2.0840.
Risk Assessment
An attacker can exploit this to execute arbitrary commands on the victim's system if the user browses or bookmarks a malicious path in GUI Vim. This can lead to full system compromise.
Recommendation
Update Vim to version 9.2.0840 or later. Also avoid browsing unknown directories in GUI Vim.
Original NVD description (English source)
Vim is an open source, command line text editor. Prior to 9.2.0840, runtime/plugin/netrwPlugin.vim loads netrw and runtime/pack/dist/opt/netrw/autoload/netrw.vim constructs Bookmarks, History, and Targets menu entries by interpolating attacker-controlled directory paths into executed :menu commands. s:NetrwBookmarkMenu(), s:NetrwTgtMenu(), g:netrw_menu_escape, EX_TRLBAR, and netrw#MakeTgt() fail to neutralize the | command separator or single quotes at five construction sites, allowing a crafted path browsed or bookmarked in GUI Vim to execute arbitrary Ex and operating-system commands. This issue is fixed in version 9.2.0840.
