Summary

CVE-2026-116843 affects Mistral Vibe before 3.0.3. Attacker-defined git filter drivers in an untrusted repository's .git/config are executed when Vibe is started with --worktree, because git worktree add applies .gitattributes and runs filter smudge, clean, or process commands before the trusted-folder check. The result is execution of attacker commands with user privileges.
