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.
