Mistral Vibe before 3.0.3 RCE via Repository-Configured gpg.program

Summary

Mistral Vibe before 3.0.3 contains a remote code execution vulnerability that allows attackers to run commands by abusing repository-configured gpg.program during project context collection. A crafted repository setting gpg.program and log.showSignature with a signed commit makes git log execute the attacker's program at session start, before any trust prompt.

Remediation

1. Inventory every mistralai mistral-vibe deployment, including staging.
2. Upgrade mistralai mistral-vibe to 3.0.3.
3. Confirm the running version after the upgrade.
