Security audit: Native interface and agentic attack surface analysis

[Copilot]

Summary

Comprehensive security assessment of JNI/JNA native bindings and LLM agent framework attack surface. Documents critical SSRF vulnerabilities and API key exposure requiring immediate remediation.

Audit Findings

Native Interface Security (JNI/JNA)

• Status: ✅ No vulnerabilities found
• Current state: No llama.cpp bindings exist; only Vosk library (properly wrapped via Using.Manager)
• Future risk: GSOC 2026 project proposes llama.cpp integration - requires mandatory security review

Agentic Security

• Status: 🔴 Critical vulnerabilities identified

Critical Issues:

1. SSRF in RAG components - UrlLoader and WebCrawlerLoader lack IP/hostname validation

   • Can access cloud metadata endpoints (169.254.169.254)
   • Can scan internal networks (10.x, 192.168.x, 172.16-31.x)
   • HTTPTool only blocks localhost

2. API key logging - ZaiClient and GeminiClient log sensitive data in DEBUG mode

   • Request/response bodies logged with Authorization headers
   • API keys in URL query parameters

3. Optional loop limits - Agent maxSteps defaults to None (unbounded)

Secure by Design:

• Shell execution: explicit command allowlist, disabled by default
• File write: path allowlist required, not in safe toolsets
• File read: system paths blocked by default

Documentation Deliverables

• docs/security/README.md - Executive summary and remediation priority
• docs/security/NATIVE_INTERFACE_SECURITY_AUDIT.md - JNI/JNA analysis
• docs/security/AGENTIC_SECURITY_AUDIT.md - Detailed vulnerability analysis with exploitation examples
• docs/security/LLAMA_CPP_SECURITY_GUIDE.md - Implementation guide for future native bindings

Total: 2,001 lines of security documentation

Recommended Actions

URGENT (24-48h):

• Add IP range validation to UrlLoader.scala, WebCrawlerLoader.scala, HTTPTool.scala
• Implement log redaction utility for API keys/sensitive data

HIGH (1 week):

• Change Agent.run() default maxSteps from None to Some(50)
• Restrict HTTPConfig default methods to GET, HEAD

Security Grade

Current: C+ (SSRF vulnerabilities block production use)
After fixes: A (best-in-class agentic security)
