Unauthorized Credential Access in Flowise

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
Flowise (npm packages `flowise` and `flowise-components`) through 3.1.4 looks up credentials by ID without filtering on the requesting user's workspace (findOneBy({ id: credentialId }) with no workspaceId condition) in several code paths: getAllOpenaiAssistants/getSingleOpenaiAssistant (GET /api/v1/openai-assistants and /api/v1/openai-assistants/:id), uploadFilesToAssistant (POST /api/v1/openai-assistants-file/upload/), deleteAssistant (DELETE /api/v1/assistants/:id, reachable by first importing a poisoned assistant row via POST /api/v1/export-import/import), and the shared helper used by getVoices (GET /api/v1/text-to-speech/voices). An authenticated user of one workspace can supply a credential UUID belonging to another workspace, causing the server to decrypt and use that workspace's OpenAI or ElevenLabs API key on the attacker's behalf. No patched version was available at the time of publication.

Executive Summary

Flowise versions up to 3.1.4 allow authenticated users in one workspace to access credentials from another workspace by exploiting improper filtering in credential lookups. The system fails to restrict credential access to the requesting user's workspace, enabling unauthorized decryption and use of API keys belonging to other workspaces.

Impact Analysis

An attacker could use this flaw to access sensitive API keys (e.g., OpenAI or ElevenLabs) from other workspaces, potentially leading to unauthorized API usage, data exfiltration, or service disruption. This could result in financial costs, reputational damage, or misuse of resources.

Compliance Impact

This vulnerability could violate compliance requirements by enabling unauthorized access to sensitive data or credentials, potentially breaching GDPR (data protection) or HIPAA (healthcare data privacy) regulations. Organizations may face legal penalties or reputational harm.

Mitigation Strategies

Upgrade Flowise to the latest patched version if available. If no patch exists, restrict user access to sensitive API endpoints and credentials. Monitor logs for unauthorized access attempts to workspace-specific resources.
