Demystifying Security Risks of AI-Powered Applications on Pre-Trained Model Hubs

Researchers conducted the first systematic security analysis of AI-powered applications on pre-trained model hubs like Hugging Face, identifying five threat categories and ten attack vectors. Their analysis of over 970,000 public AI-Apps found thousands leaking credentials, hundreds with input injection vulnerabilities, and tens with embedded backdoors, indicating active exploitation.

While lowering AI adoption barriers, these platforms introduce an unexplored attack surface, as AI-Apps are often developed by untrusted parties with weak isolation and misconfigured security settings. In this paper, we present the first systematic security analysis of AI-Apps across three leading platforms. To structure our investigation, we map the AI-App lifecycle to established risk taxonomies e.g., OWASP , identifying five threat categories and ten attack vectors ranging from generic web flaws to high-impact architectural issues. Our analysis reveals critical failures including broken access control, insecure resource reuse, insufficient input validation, and sensitive data exposure. Notably, we uncover three novel architectural vulnerabilities inherent to platform design and demonstrate how traditional issues e.g., world-readable logs are uniquely amplified in this ecosystem. To assess real-world impact, we develop an analysis framework Insightor and apply it to over 970,000 public AI-Apps. Alarmingly, we find thousands of apps leaking credentials, hundreds containing input injection vulnerabilities that allow arbitrary code execution, and tens harboring embedded backdoors -- indicating active exploitation. We have responsibly disclosed all findings to the affected platforms and developers. References & Citations Loading...
