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.
