AI Powered Q&A
Can you explain this vulnerability to me?
The vulnerability is a Server-Side Request Forgery (SSRF) in FastGPT, an AI Agent building platform. Before version 4.14.17, attackers or authenticated users with App editing privileges could exploit the fetchData function in the lafModule workflow node to send arbitrary HTTP requests to internal or private network addresses. This happens because the function uses axios to fetch user-controlled URLs without properly validating them against the application's internal network blocklist guard (isInternalAddress), effectively bypassing SSRF protections.
How can this vulnerability impact me? :
This vulnerability allows attackers to send unauthorized HTTP requests to internal or private network addresses, potentially accessing sensitive internal services or data that should be protected from external access. This can lead to information disclosure, unauthorized actions within the internal network, or further exploitation of internal systems.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should upgrade FastGPT to version 4.14.17 or later, where the SSRF issue has been patched.
Additionally, restrict or review user permissions to ensure that only trusted users have App editing privileges, as authenticated users with such privileges can exploit this vulnerability.
