Vim: Arbitrary Command Execution via Malicious `.VimballRecord` Entry Replay in `vimball.vim`

Published Aug 11, 2026

Modified 1 months ago

Fix available

Details

Vim is an open source, command line text editor. Prior to 9.2.0847, runtime/autoload/vimball.vim allows a crafted vimball member named .VimballRecord to overwrite the installation record with attacker-chosen commands. When vimball#RmVimball() later processes the matching record entry, the stored Ex commands, including operating-system commands invoked through :!, execute with the privileges of the user running Vim. This issue is fixed in version 9.2.0847.
