Mistral Vibe before 3.0.3 RCE via Git Filter Drivers in Worktree Mode
Description

Mistral Vibe before 3.0.3 contains a remote code execution vulnerability that allows attackers to run commands by defining git filter drivers in an untrusted repository's .git/config. When started with --worktree, git worktree add applies .gitattributes and runs filter smudge, clean, or process commands before the trusted-folder check, executing attacker commands with user privileges.
