CVE-2026-46483

HIGH7.0

Vim is an open source, command line text editor. Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives on Unix-like systems. The function builds :!gunzip and :!gzip -d commands using shellescape(tartail) without the {special} flag, allowing a crafted archive filename to trigger Vim cmdline-special expansion and execute shell commands in the user's context. This vulnerability is fixed in 9.2.0479.

HIGH7.3

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.
