Miggo AIRoot Cause Analysis

The commit f84ad9c introduced shell-escape to sanitize git command arguments, indicating previous vulnerable command construction patterns. All modified functions used unsanitized template string interpolation (${hash}, ${a}, ${b}) in child_process.execSync calls, making them susceptible to command injection. The CWE-78 classification confirms improper neutralization of OS command special elements. High confidence comes from the explicit addition of argument escaping in the patch and the vulnerability's CVSS score of 8.8.
