Component: Extensions (TypeScript Plugins)
Category: security
Priority: High

Summary

Zero security event logging exists across the entire extensions subsystem. OTEL captures operational metrics but no security-relevant events. No audit trail exists for plugin registrations, tool executions, config modifications, memory operations, webhook processing, subprocess executions, or authentication attempts.

Vulnerability Location

Root Cause Analysis

Direct Cause: Security logging was never implemented in the extensions subsystem. Only operational telemetry (OTEL) exists.
Underlying Cause: Security event logging was not part of the original architecture.

Impact

• Affected Systems: Extensions (TypeScript Plugins)
• Affected Users: All users of the affected component
• Affected Data: Credentials, configuration, user data

Remediation

Short-term (Immediate)

• Add authentication to all exposed endpoints
• Implement webhook signature verification
• Add rate limiting on authentication endpoints

Medium-term (Sprint)

• Deploy RBAC with least-privilege principle
• Implement multi-factor authentication
• Add constant-time token comparison

Long-term (Architecture)

• Migrate to OAuth 2.0/OIDC with PKCE
• Implement API gateway with centralized auth
• Deploy mutual TLS for service-to-service auth
