queryGitHub(): Placeholder for future GitHub Advisory Database integration - enrichVulnerability(): Multi-database enrichment pipeline - Normalization to unified Vulnerability schema with severity, references, fixed versions - Graceful error handling for network failures and API errors Co-Authored-By: Claude Sonnet 4.5 * auto-claude: subtask-5-1 - Create scripts/sast_analyzer.mjs to run Semgrep and Bandit Implemented static analysis engine following scan_dependencies.mjs pattern: - Runs Semgrep for JS/TS with --config auto and --json output - Runs Bandit for Python with -r -f json -c pyproject.toml - Handles non-zero exit codes gracefully (tools exit 1 on findings) - Parses JSON output and converts to unified Vulnerability schema - Supports --target and --format CLI flags - Gracefully handles missing tools (semgrep, bandit) - Generates ScanReport with UUID scan_id and severity summary Verification passed: JSON output with valid vulnerabilities array Co-Authored-By: Claude Sonnet 4.5 * auto-claude: subtask-6-1 - Create scripts/dast_runner.mjs with basic security test framework - Implemented DAST framework with 4 security test cases: - DAST-001: Hook handler malicious input test (XSS, command injection, path traversal) - DAST-002: Hook handler timeout enforcement (30s default) - DAST-003: Hook handler resource limits (memory/CPU) - DAST-004: Hook handler event mutation safety - Supports --target, --format (json|text), --timeout CLI flags - Returns unified ScanReport with vulnerability schema - Executes all test cases with configurable timeout - Tests malicious input patterns: XSS, SQL injection, command injection, path traversal, null bytes, large payloads - v1 scope: basic test framework for hook security testing (full agent workflow DAST is future work) Verification: - ✅ Framework loads and executes 4 test cases - ✅ Timeout enforcement working (30s default, configurable via --timeout) - ✅ JSON output with valid scan_id - ✅ Text format output working - ✅ Help output displays usage information * auto-claude: subtask-7-1 - Create scripts/runner.sh as main entry point with CLI flag parsing - Orchestrates all scanning engines (dependency, SAST, DAST, CVE) - Supports --target (required), --output, --format flags - Merges reports from all scanners using jq - Provides --help documentation - Follows openclaw-audit-watchdog/scripts/runner.sh pattern - Includes skip flags for selective scanning - Verification: --help shows --target flag * auto-claude: subtask-8-1 - Create hooks/clawsec-scanner-hook/HOOK.md with hook metadata - Added YAML frontmatter with hook name, description, and OpenClaw events - Documented hook purpose: periodic vulnerability scanning on agent:bootstrap and command:new - Described four scanning engines: dependency, SAST, DAST, CVE lookup - Added safety contract (non-blocking, read-only, configurable interval) - Documented all environment variables (core config, CVE integration, selective scanning, advanced options) - Listed required binaries (node, npm, python3, pip-audit, semgrep, bandit, jq, curl) - Follows clawsec-advisory-guardian/HOOK.md pattern Co-Authored-By: Claude Sonnet 4.5 * auto-claude: subtask-8-2 -
