Obsidian MCP Plugin - Security and Code Quality Issues

This directory contains detailed GitHub issues documenting security vulnerabilities and code quality problems found during the security audit of the Obsidian MCP Plugin.

🔴 Critical Security Issues

01. No Authentication or Authorization

• Severity: CRITICAL
• Impact: Any local application can access and manipulate the entire vault
• Fix: Implement API key authentication and CORS restrictions

02. Path Traversal Vulnerability

• Severity: CRITICAL
• Impact: Access to files outside vault, system file exposure
• Fix: Implement comprehensive path validation and sanitization

🟠 High Priority Issues

03. Missing Input Validation

• Severity: HIGH
• Impact: DoS attacks, memory exhaustion, application crashes
• Fix: Implement input validation framework with size/format limits

04. Insecure Session Management

• Severity: HIGH
• Impact: Session hijacking, unauthorized access
• Fix: Replace UUID sessions with cryptographic tokens

🟡 Medium Priority Issues

05. SOLID Principles Violations

• Severity: MEDIUM
• Impact: Difficult maintenance, tight coupling, hard to extend
• Fix: Refactor into smaller, focused classes with dependency injection

06. Large Vault Scalability

• Severity: MEDIUM
• Impact: Performance degradation with 10,000+ files
• Fix: Implement scalable path validation strategies

Quick Summary

The Obsidian MCP Plugin provides powerful functionality but has significant security vulnerabilities:

1. No authentication - Any local app can access your vault
2. Path traversal - Potential access to system files
3. No input validation - Risk of DoS and crashes
4. Weak sessions - Can be hijacked easily
5. Code quality - Difficult to maintain and extend
6. Scalability - Performance issues with large vaults

Recommended Action Plan

Immediate (Week 1)

1. Add basic API key authentication
2. Implement path traversal protection
3. Add input size limits

Short-term (Weeks 2-3)

1. Replace session management
2. Add comprehensive input validation
3. Implement rate limiting

Long-term (Month 2)

1. Refactor for SOLID principles
2. Implement scalable validation
3. Add security audit logging

Security Disclosure

If you're using this plugin in production:

1. Restrict network access to localhost only
2. Monitor for unauthorized access attempts
3. Consider alternatives until security is improved
4. Report issues responsibly to the maintainers
