CVE-2026-46483 (GCVE-0-2026-46483)

Vulnerability from cvelistv5 – Published: 2026-05-15 14:57 – Updated: 2026-05-15 15:57

Title

Vim: Command injection in tar#Vimuntar via missing shellescape {special} flag

Summary

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.

Severity ?

3.6 (Low)

      "value": "Vim is an open source, command line text editor. 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\u0027s context. This vulnerability is fixed in 9.2.0479."
