Vulnerability Title
FastGPT: Cross-team LLM request/response disclosure (IDOR) via /api/core/ai/record/getRecord
Source: CVE Program / CVE List V5
Vulnerability Description
FastGPT is a knowledge-based AI application platform. Prior to 4.15.0, GET /api/core/ai/record/getRecord authenticates the caller but loads LLM request and response traces only by requestId without team scoping, allowing any authenticated user to read another team's prompts, retrieved RAG chunks, and completions if the requestId is known. This issue is fixed in version 4.15.0.
