Short explanation

Mistral Vibe before version 2.25.5 on Windows contains an untrusted search path vulnerability that allows attackers to execute code by placing a malicious git.exe in a repository root.

Why does it matter?

By luring users into opening a crafted repository, the malicious git.exe runs at session start before any trust prompt, compromising confidentiality, integrity, and availability.

What should be done?

  • Update Mistral Vibe to version 2.25.5 or later
  • Follow vendor advisories and patch references
  • Exercise caution when opening untrusted repositories
