🛡️ Sentinel: [MEDIUM] Fix Bandit security warnings (B108, B104) - #978
Conversation
- Fixes B108 (hardcoded tmp directory) in tests/test_config.py by replacing absolute path "/tmp/cfg.yaml" with relative path "cfg.yaml"
- Fixes B104 (hardcoded bind all interfaces) in tests/test_ssrf_enhanced.py by appending a nosec directive to a false-positive mock value ("0.0.0.0")

Pull request overview
This PR reduces Bandit security-scanner noise in the test suite by addressing two flagged patterns (hardcoded /tmp usage and 0.0.0.0 literals) without changing production behavior.
Changes:
- Updated CLI argument parsing tests to use a non-
/tmpconfig path string (cfg.yaml) to avoid Bandit B108. - Added an inline
# nosec B104suppression on a mocked0.0.0.0DNS resolution tuple to avoid a Bandit false-positive in SSRF tests.

|---|---|
| tests/test_config.py | Replaces hardcoded /tmp/cfg.yaml with cfg.yaml in --config/-c argument parsing tests to eliminate B108. |
| tests/test_ssrf_enhanced.py | Adds # nosec B104 on the mocked ("0.0.0.0", 443) return to suppress an irrelevant B104 finding in a test mock. |
🚨 Severity: MEDIUM
💡 Vulnerability: Bandit linter identified potential security issues in tests: insecure usage of hardcoded temporary directories (B108) and potential binding to all interfaces (B104).
🎯 Impact: While these occur in test files and don't affect production security, resolving them removes noise from security scanners and ensures tests follow best practices for resource allocation and mocked data.
🔧 Fix:
tests/test_config.py, replaced the hardcoded/tmp/cfg.yamlpath with a relativecfg.yamlpath, which perfectly satisfies the test assertions while avoiding the B108 warning.tests/test_ssrf_enhanced.py, added a# nosec B104directive to the mock DNS resolution test since0.0.0.0is being used safely within a mock return value to test SSRF protections.✅ Verification: Ran
uv tool run bandit -r . -llto confirm that the repo no longer triggers B108 or B104 warnings, and ranuv run pytestto ensure all tests still pass (374/374).PR created automatically by Jules for task 16575550744821189167 started by @abhimehro
