CVE-2026-61644

FastGPT: /api/core/chat/record/getCollectionQuote can disclose cross-tenant dataset text due to an unbound initialId lookup

Published Jul 15, 2026 CVSS 3.1 · 7.7 High EPSS < 1% KEV · Not listed
Description
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.
