CVE-2026-47162

Vim: Vimscript Code Injection in netrw NetrwBookHistSave() via crafted directory name

CVSS 4.0 7.3 HIGHCheck source for fixed versionsKEV status unknown
Original advisory

cve-program · CVE-2026-47162

Published

Vim is an open source, command line text editor. Prior to version 9.2.0495, a Vimscript code injection vulnerability exists in s:NetrwBookHistSave() in the netrw plugin (runtime/pack/dist/opt/netrw/autoload/netrw.vim) when serializing browsed directory paths to the history file ~/.vim/.netrwhist. A directory name derived from the filesystem is interpolated into a single-quoted Vimscript string literal without escaping embedded single quotes, allowing a crafted directory name to break out of the string context and execute arbitrary Vimscript, including shell commands via system() and :!, the next time the history file is sourced. This issue has been patched in version 9.2.0495.
