CVE-2026-73076 PUBLISHED

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

Assigner: GitHub_M
Reserved: 10.08.2026 Published: 11.08.2026 Updated: 11.08.2026

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.
