# CVE-2026-122134: Mistral Vibe before 2.25.7 Code Execution via Git Filter Drivers

Status: published. Published: 2026-11-04. Updated: 2026-11-04.

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.
