CVE-2026-46483 is a command injection vulnerability in Vim versions before 9.2.0479 affecting decompression of .tgz archives on Unix-like systems. The tar#Vimuntar() function constructs external decompression commands using shellescape(tartail) without the {special} flag. Consequently, a crafted archive filename can undergo Vim command-line special expansion despite shell escaping, allowing shell commands to execute in the Vim user's context.
