Summary
Mistral Vibe versions before 2.23.3 have an RCE (remote code execution, where attackers can run commands on a victim's computer) vulnerability that lets attackers execute arbitrary commands by hiding malicious code in a repository's .git/config file. When a user runs vibe commands in a crafted repository, the malicious code is triggered through git hooks (automated scripts that git runs at certain points), giving attackers full control over what runs on the victim's system.
Solution / Mitigation
Update Mistral Vibe to version 2.23.3 or later.
