Zed code editor prior to version 0.227.1 contains a critical vulnerability that allows remote code execution when opening folders with malicious .git/config files. The vulnerability exploits the core.fsmonitor Git configuration option to execute arbitrary commands when a victim opens a folder in untrusted mode. This represents a significant security risk for developers using the Zed IDE as it could allow attackers to compromise systems through seemingly innocent project folders containing crafted Git configuration files.
