Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: Direct string concatenation of a port into execSync allows shell metacharacter injection; fixed by switching to execFileSync with an argument array.
Command Injection: User-controlled file names on Windows are passed to shell commands via execSync/spawn; two separate fixes added filename whitelist validation, indicating repeated exposure.
