- Replace passlib.CryptContext with bcrypt 4.2.1 directly (passlib is
unmaintained and only emitted warnings when paired with bcrypt 4+).
hash_password / verify_password now call bcrypt.checkpw / .hashpw, and
verify_password is hardened against empty inputs without raising.
scripts/hash_password.py + tests/conftest.py updated to match.
- status_checker.check_node() now rejects targets starting with '-' before
any subprocess invocation, defending ping/tcp paths against arg-injection
if an admin sets a check_target like '-O'.
Tests added:
- test_auth: expired JWT, malformed JWT, wrong-secret JWT, empty password
vs empty server hash, verify_password edge cases.
- test_scan: _background_scan failure path marks ScanRun failed, leaves
non-running terminal status alone, success path invokes run_scan.
- test_status_checker: ping/tcp invocations are bypassed when target or
ip starts with '-'.
Backend coverage 89% → 90%.
ping(8) -W flag is milliseconds on macOS, seconds on Linux. Code used
-W 1 for both, giving macOS a 1ms timeout that fails any host with
RTT >1ms (typical wifi/mesh is 2-10ms).
Use -W 1000 on darwin to match the intended 1s timeout. Add regression
test asserting the platform-specific value.
