CVE-2026-54602: CWE-639: Authorization Bypass Through User-Controlled Key in labring FastGPT
FastGPT versions prior to 4.15.0 contain an authorization bypass vulnerability in the GET /api/core/ai/record/getRecord endpoint. Authenticated users can access LLM request and response traces belonging to other teams if they know the requestId, due to lack of team scoping. This issue is resolved in version 4.15.0.
AI Analysis
Technical Summary
CVE-2026-54602 describes an authorization bypass vulnerability (CWE-639) in labring's FastGPT platform. The GET /api/core/ai/record/getRecord API endpoint authenticates users but fails to restrict access to LLM request and response traces by team. As a result, any authenticated user can retrieve sensitive data such as prompts, retrieved RAG chunks, and completions from other teams if they possess the requestId. The vulnerability affects all FastGPT versions prior to 4.15.0 and is fixed in 4.15.0.
Potential Impact
An attacker with valid authentication can access confidential AI request and response data from other teams, potentially exposing sensitive prompts and retrieved information. This compromises data confidentiality within the platform. There is no indication of privilege escalation or denial of service. The CVSS 4.0 score is 7.1 (high severity), reflecting the ease of exploitation and high confidentiality impact.
Mitigation Recommendations
Upgrade FastGPT to version 4.15.0 or later, where this authorization bypass vulnerability is fixed. No other mitigation or workaround is indicated. Patch status is not explicitly stated but the fix is included in version 4.15.0.
