🚨 HIGH: Framework Input Injection via LangChain/CrewAI Integration

[parmarmanojkumar]

Summary

HIGH Security Vulnerability: User input is directly passed to AI frameworks without validation, allowing framework-specific injection attacks.

Security Level: 2/5 - No input validation at integration boundary
Impact: Framework manipulation, prompt injection, resource abuse
Priority: P1 - HIGH PRIORITY

Vulnerability Details

• Raw user input sent directly to LangChain/CrewAI
• No input validation before framework processing
• Framework prompt templates vulnerable to injection
• Chain of injection attacks possible between frameworks

Code Location

• Framework improvement functions receive raw user input
• LangChain prompt template construction without sanitization
• CrewAI task creation with unvalidated input
• Custom function parameters not validated

Attack Vector

Attackers can:

• Inject malicious prompts into framework operations
• Manipulate LangChain tool execution
• Override CrewAI agent instructions
• Cause resource exhaustion through large inputs

Security Impact

• Framework behavior manipulation
• Unauthorized tool execution
• Resource exhaustion attacks
• Cross-framework injection chains

Fix Required

Implement input validation and sanitization at framework boundaries within 1 week.

Action Required

1. Add input validation schemas for all framework inputs
2. Implement framework-specific sanitization
3. Add input length and content restrictions
4. Validate framework configurations
5. Add output filtering and validation

Timeline: HIGH PRIORITY - Must be fixed within 1 week.
