Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Command Injection: Argument quoting failed to escape shell metacharacters, allowing crafted input to inject arbitrary commands. This is the highest-impact historical flaw and likely affects any code path that builds OS commands from external input.
Insecure Temporary File: Temporary files were created with default permissions, exposing them to local tampering or disclosure. Using Files.createTempFile enforces restrictive POSIX permissions.
