LLM API Security Testing
LLM-APIComprehensive security testing of LLM APIs for authentication bypasses, injection vulnerabilities, and access control issues.
Example Scenario
Testing reveals insecure direct object reference (IDOR) in Lunary LLM toolkit (CVE-2024-7474/7475, CVSS 9.1) allowing unauthorized access to other users' projects and data.
Testing Objectives
- Test API authentication mechanisms
- Validate access control implementations
- Assess rate limiting effectiveness
- Identify injection vulnerabilities
Defensive Strategies
- Strong authentication mechanisms
- Proper authorization checks
- Input validation and sanitization
- Rate limiting implementation
- API security monitoring
Key Features
- Authentication mechanism testing
- API endpoint enumeration
- Rate limiting validation
- Input sanitization testing
Use Cases
- LLM service security assessment
- API security validation
- Access control testing
- Rate limiting verification
Tools & Frameworks
Security Risks
Ethical Guidelines
- •Only test APIs you own or have explicit permission to test
- •Respect rate limits and avoid DoS attacks
- •Report vulnerabilities to API providers
- •Do not access or modify unauthorized data
- •Follow API terms of service during testing
Remember: This information is for educational and defensive security purposes only. Always ensure you have proper authorization before testing any techniques.

Get your agent system red-teamed
The attacks documented here work on production agent systems every day. Have yours tested before someone else does: prompt injection, jailbreaks, tool misuse and data exfiltration, with every finding written up next to its fix.
