🚨 CRITICAL: Unsandboxed LangChain/CrewAI Framework Execution

[parmarmanojkumar]

Summary

CRITICAL Security Vulnerability: LangChain, CrewAI, and custom frameworks execute without sandboxing or resource limitations, allowing arbitrary code execution.

Security Level: 2/5 - No framework isolation
Impact: Arbitrary code execution, resource exhaustion, system compromise
Priority: P0 - IMMEDIATE ACTION REQUIRED

Vulnerability Details

• Framework code executes with full system privileges
• No resource limits (CPU, memory, network)
• No sandboxing for framework operations
• Custom improvement functions run unrestricted

Code Location

• Framework integration examples lack security controls
• Custom improvement function execution without isolation
• LangChain tool execution without authorization
• CrewAI agent operations without boundaries

Attack Vector

Malicious actors can:

• Execute arbitrary code through framework integrations
• Exhaust system resources (CPU, memory)
• Access unauthorized system resources
• Compromise the entire NANDA adapter system

Security Impact

• Complete system compromise possible
• Resource exhaustion attacks
• Unauthorized access to system resources
• Framework vulnerabilities inherited by NANDA

Immediate Fix Required

Implement framework sandboxing and resource limits within 48 hours.

Action Required

1. Implement framework execution sandboxing
2. Add resource limits (CPU, memory, execution time)
3. Restrict network and file system access
4. Add capability restrictions for framework operations
5. Implement framework-specific security controls

Timeline: CRITICAL - Must be fixed within 48 hours.
