Fix command injection vulnerability in `src/util/git.js` by replacing `exec` with `execFile`. ## Changes - Replace `exec` with `execFile` in the `checkout` function - Pass git command arguments as array elements instead of string interpolation - Run each git command sequentially with proper error handling ## Why The `exec` function spawns a shell to execute commands, which means shell metacharacters in user-controlled input (like the `hash` parameter) could be interpreted and executed. By using `execFile`, arguments are passed directly to the executable without shell interpretation, preventing injection attacks even if malicious input like `; rm -rf /` or `$(command)` is provided. ## Semgrep Finding Details Untrusted input might be injected into a command executed by the application, which can lead to a command injection vulnerability. An attacker can execute arbitrary commands, potentially gaining complete control of the system. To prevent this vulnerability, avoid executing OS commands with user input. If this is unavoidable, validate and sanitize the user input, and use safe methods for executing the commands.
