const { execSync } = require('child_process');

execSync(
`codesign -s ${teamID} --deep --force --options runtime --entitlements ${entitlementsPath} ${config.app}`

Fix the issue will replace the use of execSync with execFileSync, which allows us to pass the command and its arguments separately. This approach avoids shell interpretation of the arguments, mitigating the risk of command injection. Specifically:

  1. The codesign command will be passed as the first argument to execFileSync.
  2. The dynamic components (teamID, entitlementsPath, and config.app) will be passed as separate arguments in an array.
  3. This change ensures that special characters in the inputs are treated as literal values and not interpreted by the shell.
