🔧 Security Best Practices

For Developers

1. Always validate user input
2. Use parameterized queries
3. Implement proper error handling
4. Follow the principle of least privilege

For Operations

1. Keep security patches up to date
2. Monitor security logs regularly
3. Implement network security controls
4. Regular security assessments

🚨 Security Incident Response

• Report security issues immediately
• Follow the established incident response procedure
• Document and learn from security events
• Regular security training and awareness

⚠️ Known Vulnerability Acceptances

CVE-2024-23342 (ecdsa 0.19.1) - Accepted Risk

Package: ecdsa 0.19.1 (transitive dependency of python-jose)

Vulnerability: Minerva timing attack on P-256 curve. The sign_digest() API and timing signatures could leak internal nonce, potentially allowing private key discovery.

Why Accepted:

1. No fix available: Maintainers consider side-channel attacks out of scope
2. Limited exposure: JWT signing occurs server-side in protected environment
3. Attack difficulty: Timing attacks require precise measurement, difficult remotely
4. Verification unaffected: Only signing operations are vulnerable
5. Alternative trade-offs: PyJWT has its own considerations

Mitigation:

• Server-side JWT operations in controlled environment
• Network-level protections between services
• Regular monitoring for alternative libraries

Review Date: January 2026 | Next Review: April 2026

CVE-2026-0621 (@modelcontextprotocol/sdk) - Accepted Risk

Package: @modelcontextprotocol/sdk 1.25.1 (development tooling only)

Vulnerability: ReDoS (Regular Expression Denial of Service) in UriTemplate class when processing RFC 6570 exploded array patterns. Malicious URIs can cause Node.js process to become unresponsive.

Severity: High (CVSS 8.7)

Why Accepted:

1. Development tooling only: MCP servers run locally for Copilot integration, not in production
2. No fix available: Upstream fix pending in Anthropic's SDK
3. Local execution: Attack surface limited to local development machine
4. No network exposure: MCP servers communicate via stdio, not exposed to network
5. Controlled inputs: Only accepts requests from VS Code Copilot, not arbitrary network traffic

Mitigation:

• MCP servers are gitignored development tools
• Never run MCP servers in production environment
• Monitor for upstream fix release
• Consider alternative patterns if vulnerability becomes exploitable

Review Date: January 2026 | Next Review: February 2026 (check for upstream fix)

CVE-2025-26319 (tmp) - Accepted Risk

Package: tmp 0.0.33, 0.1.0 (transitive dependency of @lhci/cli dev tooling)

Vulnerability: Arbitrary temporary file/directory write via symbolic link dir parameter. Attacker with control over the dir option can write outside intended temp directory.

Severity: Low (CVSS 4.8)

Why Accepted:

1. Development tooling only: tmp is used by Lighthouse CI (@lhci/cli) for local testing
2. No production exposure: Package never runs in production environment
3. Transitive dependency: Cannot update directly; fix requires upstream @lhci/cli update
4. Local execution: Attack would require local code execution (already compromised)
5. No user input: Temp directories created programmatically, not from user input

Mitigation:

• @lhci/cli only runs in CI and local development
• Never use in production deployments
• Monitor for upstream fix in @lhci/cli
• Fixed version 0.2.4+ already used by selenium-webdriver path

Review Date: January 2026 | Next Review: April 2026
