Description

This security bulletin contains information about 1 vulnerability.


1) OS Command Injection (CVE-ID: CVE-2026-46483)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to execute arbitrary shell commands.

The vulnerability exists due to improper neutralization of special elements in tar#Vimuntar() in runtime/autoload/tar.vim when decompressing .tgz archives via :Vimuntar on Unix-like systems. A remote attacker can supply a crafted archive filename to execute arbitrary shell commands.

User interaction is required to open the crafted file and invoke the non-routine :Vimuntar command, and only Unix-like systems with the tar plugin enabled are vulnerable.
