CVE-2026-47162 — Vim: Vimscript Code Injection in netrw NetrwBookHistSave() via crafted directory name

Description (CNA)

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.

A flaw was found in Vim, an open-source text editor. This vulnerability, located in the netrw plugin, involves a code injection issue when the editor processes directory paths. A malicious directory name, if crafted by an attacker, could bypass security measures and allow for the execution of unauthorized commands. This could lead to arbitrary code execution on the affected system.
