[HIGH] Docker Security Hardening - Multi-Stage Build Vulnerabilities

[busybox42]

Problem: Dockerfile contains security vulnerabilities despite attempting hardening measures.

Current State: Security issues in Docker configuration:

• Builder stage has unnecessary packages (git, gcc, musl-dev)
• CGO_ENABLED=1 for plugins creates attack surface
• Base image debian:bookworm-slim has known vulnerabilities
• Python3 installation without security updates
• Missing security scanning in CI/CD

Security Implications:

• Supply chain attacks via build dependencies
• Container escape via CGO vulnerabilities
• Runtime privilege escalation opportunities
• Outdated packages with known CVEs

Technical Details:
File locations: /Dockerfile:1-45
Functions affected: Multi-stage build process, plugin compilation
Dependencies: Container runtime security, plugin system

Expected Outcome: Hardened multi-stage build with minimal attack surface and security scanning

Acceptance Criteria:

• Use distroless or scratch base image
• Implement security scanning in build process
• Minimize CGO usage in plugins
• Add vulnerability monitoring
• Document security measures
