High advisory for Mistral Vibe

Advisory overview

Mistral Vibe before 2.25.7 contains a remote code execution vulnerability that allows attackers to run commands by configuring malicious Git clean or process filter drivers in a repository. When a user opens a crafted repository, ProjectContextProvider._fetch_git_status runs git status at startup, invoking the filters and executing commands with user privileges before any trust prompt.
