The Node.js release schedule is evolving significantly starting with Node.js 27:
| Aspect | Old Model (≤26.x) | New Model (≥27.x) |
|---|---|---|
| Major releases | 2 per year (April + October) | 1 per year (April) |
| LTS promotion | Even-numbered only (October) | Every release becomes LTS (October) |
| Odd/even distinction | Odd = Current-only, Even = LTS | No distinction — all releases get LTS |
| Version numbering | Sequential | Aligned to calendar year (27 in 2027, 28 in 2028) |
| Alpha channel | N/A | 6-month alpha phase (Oct–Mar) with semver-major changes |
| Total support window | ~36 months (LTS only) | 36 months from first Current release to EOL |
Impact on Vulnerability Management:
- Simplified upgrade planning: Every release becomes LTS, eliminating odd/even skip patterns
- Annual upgrade cadence: One major Node.js upgrade per year
- Alpha testing in CI: Integrate alpha releases for early compatibility detection
- Reduced support lines: Fewer active versions simplifies patch management
TypeScript follows a rapid release cadence affecting all Node.js projects:
| Version | Status | Key Changes | Impact on Hack23 Projects |
|---|---|---|---|
| TypeScript 5.x | ✅ Current Production | Decorators, satisfies, module resolution |
All Node.js projects using TS 5.9.x |
| TypeScript 6.0 | 🔄 Released | Native go-to-definition, --erasableSyntaxOnly, improved DX |
Upgrade planned post-stability validation |
| TypeScript 7.x | 🔮 Future | Next major evolution | Track TypeScript roadmap for breaking changes |
TypeScript Migration Strategy:
- Minor Releases (5.x→5.y): Auto-merge via Dependabot with CI validation
- Major Releases (5→6→7): Dedicated migration PR with full test suite validation and CEO review
- Strict Mode: All projects enforce
strict: truefor maximum type safety
🤖 Agent Access to Security Tools:
Per 🤖 AI Policy least-privilege principles, agents have controlled access to security tools:
| Security Tool | Agent Access Level | Agent Operations | CEO Approval Required |
|---|---|---|---|
| SonarCloud | Read + Analysis | Quality metric retrieval, trend analysis | Configuration changes only |
| FOSSA | Read + Analysis | License scan review, vulnerability assessment | Policy updates only |
| GitHub Security APIs | Read + PR Creation | Dependabot review, security alert triage | Merge operations |
| GitHub Actions | Read + Trigger | Automated evidence generation, CI/CD workflows | Configuration changes only |
| OpenSSF Scorecard | Read-only | Score monitoring, degradation alerts | N/A (read-only) |
🔧 Curator-Agent Security Tool Management:
- MCP Configuration: Curator-agent maintains
.github/copilot-mcp.jsonsecurity tool integrations with CEO approval - Tool Permissions: Security tool access scoped per agent type (task vs. specialist) following least-privilege
- Audit Trails: All agent security tool interactions logged and reviewable via GitHub Actions logs
- Configuration Drift: Automated detection of unauthorized security tool configuration changes

| Agent Type | Vulnerability Management Responsibilities | Escalation Criteria |
|---|---|---|
| 🔧 Curator-Agent | Security tool configuration, MCP server management, agent permission oversight | Configuration changes require CEO approval |
| 📋 Task Agents | Vulnerability discovery, triage, impact assessment, evidence generation | High and Critical vulnerabilities (CVSS ≥7.0) |
| 👷 Security Specialist | Remediation implementation, patch deployment, configuration fixes | Breaking changes, architectural modifications |
| 🧪 Test Specialist | Remediation validation, regression testing, security test updates | Test failures, coverage degradation |

GitHub Actions & ISMS Integration:
- Vulnerability scan results automatically exported to evidence format via CI/CD workflows
- OpenSSF Scorecard badges tracked and archived
- SLSA attestations linked to vulnerability remediation PRs
- SonarCloud/FOSSA scan results integrated with compliance assessments
Agent Least-Privilege Principles:
- Agents follow read-only access except during approved remediation PRs per 🤖 AI Policy
- All agent-created PRs require CEO approval before merge per 🎯 Information Security Strategy
- All agent actions subject to PR review and CI/CD gates per 🛠️ Secure Development Policy
- Agent configurations managed by curator-agent with CEO approval
- Agent access to security tools (SonarCloud, FOSSA, GitHub Security APIs) is restricted to specific operations with audit trails

Given Hack23 AB's adoption of AI agents for development and operations, OWASP LLM-specific vulnerabilities require specialized handling beyond traditional application security controls.
Severity Classification:
- All LLM vulnerabilities treated as High severity minimum regardless of CVSS scoring
- LLM01 (Prompt Injection), LLM02 (Information Disclosure), and LLM05 (Output Handling) escalated to Critical priority
- Traditional CVSS scoring supplemented with LLM-specific risk assessment per 📊 Risk Assessment Methodology
Detection and Monitoring:
- Agent Profile Security Reviews: Curator-agent reviews all agent profile changes for security implications
- MCP Configuration Auditing: Weekly audit of MCP server configurations for credential exposure risks
- Agent Permission Analysis: Automated scanning of agent tool permissions for least-privilege violations
- Code Generation Review: Security specialist agents review all AI-generated code changes for vulnerability patterns
Remediation Workflow:
- LLM01 (Prompt Injection): Immediate agent profile isolation, input validation implementation, context sanitization
- LLM02 (Information Disclosure): Context purging, credential rotation, output filtering, access log review, incident response activation
- LLM03 (Supply Chain): Emergency dependency scanning, vendor notification, alternative LLM evaluation
- LLM04 (Data Poisoning): Vendor security review escalation, model version validation, alternative LLM provider assessment (note: moderate risk mitigated by pre-trained-only policy)
- LLM05 (Output Handling): Output encoding, sanitization rules, downstream validation, template hardening
- LLM06 (Excessive Agency): Permission revocation, capability restriction, CEO approval workflow enforcement
- LLM07 (Prompt Leakage): Prompt configuration review, context separation validation, agent profile sanitization
- LLM08 (Vector Weaknesses): Vector database access review, embedding integrity validation, AWS Bedrock security assessment (applicable upon Q1 2026 deployment)
- LLM09 (Misinformation): Enhanced human review requirements, automated quality gates, test coverage mandates
- LLM10 (Unbounded Consumption): Rate limit enforcement, budget threshold review, API quota adjustment, cost monitoring alert tuning
CEO Approval Requirements:
- All LLM vulnerability remediation requires CEO review and approval per 🤖 AI Policy
- Critical LLM vulnerabilities (LLM01, LLM02 (Information Disclosure), LLM05 (Output Handling)) escalated immediately to CEO
- Agent configuration changes addressing LLM vulnerabilities reviewed within 24 hours
- New agent capabilities or tool integrations subject to LLM security assessment
