CVE-2026-61644: CWE-863: Incorrect Authorization in labring FastGPT
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.
AI Analysis
Technical Summary
FastGPT's POST /api/core/chat/record/getCollectionQuote endpoint performs authentication on the caller's chat and collection context but fails to bind the initialId center-node lookup to the authorized context. This allows a low-privileged tenant user to supply another tenant's dataset data id as initialId, resulting in unauthorized disclosure of foreign dataset quote or full-text content. The vulnerability affects versions from 4.14.17 until 4.15.0-beta5 and is resolved in 4.15.0-beta5.
Potential Impact
The vulnerability allows unauthorized read access to dataset quote or full-text content from other tenants, leading to a confidentiality breach. The CVSS 3.1 score is 7.7 (High), reflecting network attack vector, low attack complexity, low privileges required, no user interaction, scope change, and high confidentiality impact without integrity or availability impact.
Mitigation Recommendations
A fix is available in FastGPT version 4.15.0-beta5. Users should upgrade to this version or later to remediate the vulnerability. No other official remediation or temporary fixes are documented. Patch status is not explicitly stated beyond the fixed version, so users should verify with vendor advisories for any additional guidance.
