Title

Flowise: Information Disclosure in GET /api/v1/upsert-history returns the entire server-wide upsert history

Summary

Flowise is a drag-and-drop user interface for building customized large language model (LLM) flows. Prior to 3.1.3, Flowise GET /api/v1/upsert-history returns the entire server-wide upsert history instead of being scoped to the requesting user, tenant, or workspace. The response can exceed 100MB and includes sensitive configuration data, including Vector Store settings such as Qdrant Server URL and collection name. The observed behavior indicates missing or insufficient authorization checks, workspace/project/tenant isolation, and pagination or limits, exposing integration parameters and infrastructure details that may enable further targeted attacks. This issue is fixed in version 3.1.3.

Severity

8.3 (High)

Vulnerability from github – Published: 2026-08-04 17:57 – Updated: 2026-08-04 17:57

Summary

Flowise: Information Disclosure in GET /api/v1/upsert-history returns the entire server-wide upsert history

Details

Summary

The GET /api/v1/upsert-history endpoint returns the entire server-wide upsert history (response size >100MB) instead of being scoped to the requesting user/tenant/workspace. The response includes sensitive configuration data (e.g., Vector Store settings such as Qdrant Server URL and collection name), resulting in a High severity information disclosure that may enable further targeted attacks.

Details

Affected endpoint: GET /api/v1/upsert-history
Observed behavior: The API returns global upsert history for the whole server, indicating missing/insufficient:
Authorization checks (RBAC/user-based access control)
Data scoping (workspace/project/tenant isolation)
Pagination/limits (excessive data exposure and very large responses)
Sensitive data exposure: The returned history contains integration parameters and infrastructure details. Example excerpt from the response: ```json { "label": "Qdrant", "name": "qdrant", "category": "Vector Stores", "id": "qdrant_0", "paramValues": [ { "label": "Qdrant Server URL", "name": "qdrantServerUrl", "type": "string", "value": "https://7f60f255-f7fd-4a1c-a734-fbcf904f9f85.europe-west3-0.gcp.cloud.qdrant.io" }, { "label": "Qdrant Collection Name", "name": "qdrantCollection", "type": "string", "value": "fair-herring-azure" }, { "label": "Vector Dimension", "name": "qdrantVectorDimension", "type": "number", "value": 1536 }, { "label": "Content Key", "name": "contentPayloadKey", "type": "string", "value": "content" }, { "label": "Metadata Key", "name": "metadataPayloadKey", "type": "string", "value": "metadata" }, { "label": "Similarity", "name": "qdrantSimilarity", "type": "options", "value": "Cosine" } ] }

POC

Impact

Vulnerability type: Information Disclosure / Broken Access Control (missing authorization and/or missing tenant/workspace scoping)
Who is impacted: All users/tenants/workspaces whose upsert history and configuration data are included in the server-wide history
Security consequences:
Exposure of infrastructure/integration details (e.g., Qdrant endpoint URLs, collection names, vector dimensions), enabling reconnaissance and targeted follow-up attacks
Leakage of internal schema/pipeline details (e.g., content/metadata keys)
Potential resource abuse: repeated downloads of a >100MB response can increase bandwidth/CPU/memory load (amplifying DoS risk)

Severity

8.3 (High)
