FKIE_CVE-2026-61644

Vulnerability from fkie_nvd - Published: 2026-07-15 15:16 - Updated: 2026-07-15 19:50
Severity
7.7 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
Summary
FastGPT is a knowledge-based AI application platform. From 4.14.17 until 4.15.0-beta5, the POST /api/core/chat/record/getCollectionQuote endpoint authenticates the caller's chat and collection context, but the initialId center-node lookup is not bound to that authorized context. A low-privileged tenant user can call the endpoint with valid attacker-owned appId, chatId, chatItemDataId, and collectionId values while supplying another tenant's dataset data id as initialId, causing the response to include foreign dataset quote or full-text content. This issue is fixed in version 4.15.0-beta5.
