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.
