Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Command Injection: Unsanitized input containing auth tokens was written directly to a bird credentials file, allowing command injection when the file was subsequently sourced by a shell script. This was mitigated by applying shlex.quote to the injected values.
Insecure Temporary File: Writing configurations containing sensitive credentials using standard open() created a TOCTOU window where files were briefly world-readable before permissions could be restricted. This was fixed by using os.open with O_CREAT and mode 0o600.
