remyluslosius · claude · remyluslosius · commit 015b7470121e · 2025-11-03T05:22:01.000-05:00
Fixed all ERROR, WARNING, and NOTE severity issues across 15 files: ERROR Severity (3 issues): - Fixed check_permission() calls with wrong arguments (8 instances) - host_security_discovery.py: Changed from 2-arg to 3-arg signature - host_network_discovery.py: Split "hosts:read" into ("hosts", "read") - Fixed non-iterable enum iteration in plugin_registry_service.py - Added explicit list() conversion for PluginStatus enum WARNING Severity (5 issues): - Removed 4 unnecessary pass statements in ssh_settings.py - Fixed unreachable code in rule_specific_scanner.py - Enabled remediation success rate calculation logic - Changed "if False:" to proper condition check NOTE Severity (39 issues): - Fixed 20 bare except statements (changed to "except Exception:") - scap_content.py: 7 instances - scans.py: 7 instances - remove_legacy_credentials.py: 3 instances - remediation.py, scap_import.py, capabilities.py: 3 instances - Removed 5 duplicate "import json" statements - scans.py: 3 duplicates removed - rule_scanning.py: 2 duplicates removed - Removed 2 unused import statements - error_handling.py, compliance_rules_api.py: unused json imports - Removed 2 unused variables - system_info_sanitization.py: _error_sanitization_service - system_settings_unified.py: _scheduler Security Impact: - Bare except: blocks now properly allow system exits (KeyboardInterrupt) - RBAC permission checks use correct 3-argument signature - Dead code eliminated, reducing attack surface Testing: - All files pass Python syntax validation - Docker build completes successfully - All services healthy (backend, frontend, databases, workers) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
