# Security Policy
## Scope
This repository contains **documentation and educational templates** for Claude Code. It does not include executable code that processes user input or runs in production environments.
**Security concerns specific to this repository:**
- Documentation accuracy for security practices
- Template code quality and security patterns
- Threat database integrity ([`machine-readable/threat-db.yaml`](./machine-readable/threat-db.yaml))
**Out of scope:**
- Security vulnerabilities in Claude Code CLI itself → Report to [Anthropic](https://github.com/anthropics/claude-code/security)
- Security issues in MCP servers → Report to respective server maintainers
## Reporting a Security Issue
If you discover a security concern related to this guide (examples: malicious template, incorrect security advice, threat database inaccuracies), please:
1. **Email**: florian.bruniaux@methode-aristote.fr
- Subject: `[SECURITY] Claude Code Guide - Brief Description`
- Include: Affected file/section, description, impact assessment
2. **GitHub Private Disclosure**: Use [Security Advisories](../../security/advisories/new) for sensitive issues

## Security Maintenance
**Threat Database Updates**: The threat intelligence database is updated based on:
- CVE announcements and security advisories
- Community reports of malicious skills/MCP servers
- Anthropic security bulletins
- Academic research (e.g., prompt injection papers)
**Audit Schedule**:
- Weekly review of new MCP servers and skills
- Monthly audit of security documentation accuracy
- Quarterly full threat database refresh
**Last Updated**: 2026-02-11 (v3.26.0)
## Coordinated Disclosure
If you're a security researcher and find issues affecting multiple repositories in the Claude Code ecosystem:
1. Email us first (coordinated disclosure preferred)
