CVE-2026-54602

HIGH

FastGPT: Cross-team LLM request/response disclosure (IDOR) via /api/core/ai/record/getRecord

Title source: cna
STIX 2.1

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.
