Summary
A vulnerability in Vim allows remote attackers to execute arbitrary commands by crafting a malicious .VimballRecord file that injects OS commands executed when processed by the vimball#RmVimball() function.
Remediation
Avoid installing or removing vimballs from untrusted sources. This vulnerability relies on a user processing a malicious vimball, which then injects commands that are executed during a subsequent vimball operation. Exercise caution when handling vimball files from unknown or unverified origins.

01
What, why and how
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.

This issue is fixed in version 9.2.0847.
Why
Untrusted data can cross into a code-evaluation path and be interpreted as executable instructions.
How
An attacker operating through local access may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No confirmed evidence
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material ?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.None recorded
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
Likely attack path
local access → Improper Control of Generation of Code ('Code Injection') → cause the confidentiality, integrity or availability impact described by the vendor

CWE-94: Improper Control of Generation of Code ('Code Injection').
