Prior to 9.2.0479, a command injection vulnerability exists in tar#Vimuntar() in\nruntime/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.
